Harnessing the exhaustive resources of synthetic plasma, the plasma gun meets the critical requirement of low cost, abundant ammunition for today's highly mobile military.''

Capable of sustained firepower due to the latest advancements in plasma injector technology, this weapons' light weight and high yield make it desirable for most combat scenarios.

Always on the forefront of technology, the UAC is making safer worlds through superior firepower.

Alpha Labs Introduction
Creator: UAC PR Date: 01/15/41 Alpha Labs: Past, Present and Future

''Welcome to the Alpha Labs. Formerly designated phase 1 by the Union Aerospace offworld research division, the Alpha Labs began construction on October 29th, 2095 and became fully operational July 17th, 2130.''

Originally created as the prime science and research facility, Alpha Labs are responsible for the development of leading edge technology, such as the Elemental Phase Deconstructor, Hydrocon and Molecular Fuel Storage Compressor all presently being utilized right here in the Alpha Labs.

These endeavors have allowed for much needed expansion into the UAC's current leading research facility, Delta Labs, where Union Aerospace is opening all new opportunities in research and development.

With continued investment and hard work, the Union Aerospace Corporation strives for excellence and is committed to building a better tomorrow.

Elemental Phase Deconstructor
Creator: UAC PR Date: 04/15/45 Information on the EPD system

''For generations humankind has lived under the looming spectre of slowly dwindling natural resources. Our new ventures on planets like Mars have only intensified our need to find fresh sources for metals, petrochemicals, food, water and even air.''

To meet that need UAC researchers have developed dramatic solutions, solutions that will soon pay off for the UAC, its investors and indeed the entire human race.

''Mars itself is our chief ally and the key to our solution. Look around at its vast red deserts, rich in naturally occurring iron oxides, they are the raw materials of our future.''

We have developed a process that destabilizes the atomic structure of pulverized iron oxide and separates it into subatomic particles which are then siphoned off to create new elements.

''Like alchemists of old the Elemental Phase Deconstructor allows us to transform red martian soil into clean air, fresh water and hydrogen fuel, the building blocks for a sustainable human friendly martian environment. And this is only the beginning.''

''With continued research we envision creating evermore complex molecules, even organic matter itself. Atom by atom the UAC is building an even brighter future for humankind.''

Hydrocon
Creator: UAC PR Date: 04/15/45 Information on the Hydrocon system

''Safer worlds for everyone. For centuries people on earth have waged war over two things vital to human existence, fuel and water. As part of its ongoing commitment to create safer worlds for everyone, the UAC recently unveiled its development of the Hydrocon.''

''Though still in its prototype stages, the Hydrocon will in one dramatic move, forever end all shortages of water and fuel. By splitting iron oxide molecules the Hydrocon produces oxygen and hydrogen cleanly and safely without the need for large amounts of electricity.''

The Hydrocon is then used for hydrogen fuel, a substance so versatile and clean that it can be used in everything from home appliances to today's most demanding rocket engines.

A side benefit of producing this fuel is an endless supply of pure spring-like water that is more refined than any earth bound spring.

We envision a world where technology such as the Hydrocon can be used to end drought and civil strife in impoverished nations where water or fuel have been in short supply.

While always at the forefront of scientific research and development, Union Aerospace hopes that the creation of the Hydrocon will continue to make safer worlds for everyone.

Molecular Fuel Storage Compactor
Creator: UAC PR Date: 04/15/45 Information on the MFS system

''Since the dawn of the space age, Union Aerospace has been at the forefront of not only developing new technology, but pushing those developments to even more daring extremes. With an abundant production of hydrogen fuel, thanks to the Hydrocon, the specialist teams ask the big question: "Can we devise a way to store and deliver that fuel to make the dream of deep space research a reality?" The answer has been a resounding YES!

''Under the direction of Dr Malcolm Betruger, key UAC scientists have made startling new discoveries in the field of quantum physics and with them they have been able to use the actual space between electrons and protons in a molecule as a storage medium for fuel in our interplanetary antimatter drives.

''Now fuel that would once take up half the payload of an interplanetary ship, only occupies a fraction of that space. You are looking at the Molecular Fuel Storage Compactor. The MFS Compressor is yet another UAC marvel that brings the dream of reaching and colonizing the most distant planets closer to a reality. The UAC has long made safer worlds for everyone and now they will bring worlds even closer than you could ever imagine.''

Mach-2 Chain Gun Briefing
Creator: UAC Advanced Weapons Date: 03/20/42 Informational video on the Mach-2 Chain Gun

''In a quest to provide armies with a well balanced set of weapons, the UAC look to the past when designing and manufacturing the newest line of Mach-2 Chain Guns. The retro style and mechanical sturdiness of the Chain Gun is must for all hardened combat veterans.''

''Early adapters have nicknamed it "Saw" with its armor piercing 30 caliber bullets, the Chain Gun is capable of literally cutting opponents in two. Packed with all the punch you need in close combat fighting the Chain Gun delivers unparallelled reliability and functionality. Always on the forefront of technology, the UAC is making safer worlds through superior firepower.''

Maintenance Safety Video
Creator: Central Authority Date: 10/05/45 Maintenance Department Safety Video

''Welcome to the UAC maintenance department. This video will provide you with the necessary tools and information to do your job efficiently and safely. A safe worker is a happy worker and your safety is our number one priority at UAC. Observe all signs and follow all procedures to keep you and your coworkers out of harm's way.

''Cleanup is one of the most important aspects of what we do in maintenance. This phase of our job keeps everyone safe and research has shown that working in a clean and toxic free environment has a positive benefit on overall productivity.

''Power generation on Mars produces two byproducts - steam and green goo. We vent the steam all over the base through vents, floor grates, cleverly placed pipes and pretty much anyplace else. The goo is the result of the MFS process reacting with core elements in the martian soil. It is not radioactive but it is quite toxic.''

''Remove all toxic spills at once, HAZMAT suits are the best way to protect yourself when a spill occurs. And if you happen to come into contact with the goo, report immediately to a medical station for a scrubdown. After a few days in confinement you should be ready to report back to work. Report any rule violations to your immediate supervisor and don't forget to read you employee handbook for additional rules and information.''

Teleportation Experiments
Creator: Ian McCormick Date: 11/15/45 Results of the human teleportation experiments

''My name is Ian McCormick and I am a research specialist stationed on Mars, working for the UAC. My primary job is or rather was to assist Dr Malcolm Betruger in a variety of experiments, though for the past year we've been focusing almost exclusively on teleportation. I don't know if I'll make it out of here alive so I'm recording this video log to let someone know what happened and with that knowledge, prevent it from happening again.''

''Initially the teleportation experiments were amazing. We were creating a new science and the prospect of it changing our way of life were, well they were outstanding. I was proud to be associated with such an amazing project and someone as talented as Dr. Betruger.''

''We noticed early on, probably before we had completed maybe a dozen successful tests that there was a variable delay during the teleportation. The objects are broken down at the quantum level, transported and then reassembled. Each stage of the process should have been instantaneous but it wasn't and we didn't know why. We sent a video droid through and were shocked at the images it sent back. Just a few frames of video right before the droid came back through, showed what appeared to be several sets of eyes looking directly at the probe. We had just found a living breathing creature that was not human.''

''Betruger immediately sent out a request for volunteers. He specifically wanted UAC security force members because he wanted to capture one of these creatures. [Sigh] I've made a lot of mistakes but I am most ashamed in my involvement during the next phase. To get medical clearance to send human subjects through the device, I... I doctored up several of our reports to indicate that we had performed living tissue experiments. I did not regret it at the time but a few days later when our third test subject came back... he was chewing off his own fingers. It seemed he was clinically insane.''

''We started sending teams in about once every two days. The teams reported nightmarish experiences and sightings of things that ultimately made us conclude that the other dimension was not just another dimension. It was Hell and the creatures we were bringing back, demons.''

''And then Betruger, he went through the portal himself. I don't know what he was thinking. It was an unscheduled trip and he just went and we couldn't stop him... And when he came back, he had changed. He sounded and looked the same but he just, ..., I don't know, he was just... different. And then he did the unthinkable: He took the Soul Cube, the device that was discovered in the ruins, into the portal. The portal stabilizers just started to fail and then... living hell erupted into the base.''

''Oh, we were stupid for not destroying the portals as soon as we realized what was on the other side. Oh God, forgive me. I blame myself for my part in this. Please someone, never let this happen again. Uh, I'm sorry. Ian McCormick.''

Specimen Stasis Museum
Creator: Central Authority Date: 10/05/45 Demon Museum

''Welcome to the Delta Complex Stasis Chambers. This facility was constructed to house and study the extra dimensional beings which were recovered during some of the first teleporter tests originating from Delta Labs 3.''

''While little is known about their native environment, the specimens appear to be carbon based lifeforms with extremely high heat tolerances. The epidermal tissue is extremely resilient to abrasion or incision which has complicated internal studies.''

''Observational studies have shown incredible strength and agility as well as the ability of some specimens to manifest and control cohesive plasma masses. The method by which these plasma masses are created is yet unknown.''

''It is believed that the specimens possess a rudimentary intelligence and social structure as was demonstrated during the first tragic expeditions through the portal. While the cost in human life has been great in acquiring these specimens, we hope to one day complete genomic mapping and begin to answer the many questions we have about these entities.''

Soul Cube
Creator: Central Authority Date: 10/05/45 Central Authority Research Archive

''What you see before you is a relic code named U1 or simply Soul Cube. It was discovered in 2104, located in a geographic region where UAC researchers have unearthed evidence of a long lost civilization.

We know nothing of this civilization other than they existed and that they were all wiped out in some type of cataclysmic event according to what we've been able to decode from stone tablets found throughout the ruins.

What clues we've been able to piece together reveal a culturally advanced society, whose technology can only be described as mystic as evidenced by U1's strange characteristics.

''Efforts to further examine U1 have been futile. Mass spectrometer and radiation scanning methods have failed to provide reliable identification of the molecular makeup of this artifact. The object cannot be weighed and in all tests we've been unable to determine its mass.''

''All attempts to physically manipulate or open the artifact have been met with no success. We also have had no success in deciphering the symbols adorning U1. What we do know is the thermographic readings are constant, unwavering temperature of 98.8 Fahrenheit. Our research continues and we hope that with continued investment and research we can one day soon learn to exploit the technologies that make up U1.''

BFG 9000 Briefing
Creator: UAC Advanced Weapons Date: 10/10/45 Informational video on the BFG 9000

''Representing the pinnacle of UAC research and design, the BFG 9000 is the most advanced firearm ever designed. Fully self contained and deployed is a handheld platform it is capable of an excessive amount of fire power. The BFG 9000 contains sophisticated friend or foe technology that discriminates targets in real time.''

''Each projectile contains a small but very powerful computer core that actively maintains targeting and delivers a stream charge down each beam to soften targets before detonation. The detonation stage of the projectile is devastating. Targets within 15 meters of the flashpoint are not likely to survive.''

''While not recommended for small quarter combat, the BFG 9000 is ideal in the field and against movable targets. The only foreseeable defense is small arms ballistics. If the projectile is destroyed before exploding, the computer core cannot process the final fusion reaction, resulting in a less than optimal detonation. For more information contact the UAC's Advanced Weapons Department.''

Ancient Civilization
Creator: Pierce Rogers Lead Archaeologist Date: 08/21/45 What we know about the ancient civilization and the artifacts found

''This is Dr. Pierce Rogers, lead archeologist currently stationed on Mars. As the preliminary report had suggested, we have made some amazing discoveries here on Mars. Life on Mars has long been theorized but we never imagined anything like this. The initial chamber was discovered in 2115. It leads into what is now known as Site 1.''

''Site 1 is the largest of the sites and we are still actively working there. It is made up of a series of chambers and connecting tunnels. All of which are covered in glyphs and symbols. Using the UAC pattern processor, we have found we have been able to understand some of the glyphs and from them here is what we have learned.''

''The ancient people looked like us, at least to the extent that they were bipedal and were similar in shape and size. Their level of technology was astounding. For instance, the glyphs at each site were carved into the rock by some sort machine and each one is precisely cut from the stone. It far exceeds the precision of anything we can do. They have a social structure that seemed very aristocratic, with a lot of emphasis on social stature and structure.''

''Site 2, is a much smaller set of chambers, mostly containing burial sites, temples and various amounts of individual artifacts. This site has been photographed and cleared out and all materials back on Earth for study and review.''

''Site 3 produced our prized artifact, what we call the Soul Cube. If you have read or seen the other material, you probably know that this once grand civilization was attacked by some unknown force. And if we can believe what was written in stone, they sacrificed much of their society to drive the invaders back. There are official reports filed on the Soul Cube, sent to the administration.''

''We also recovered several other device type artifacts. They are not as ornate as the Soul Cube, but each appears unique. We are still learning how to interpret all of the glyphs and hopefully once we have that completed, the science teams can provide more detailed information on their technology. These are truly unique and special times for archeologists.''

Tablets
Central Authority Date: 10/05/45 Central Authority Research Archive

''Setting new standards in both archeological discovery and analysis, the UAC is proud to showcase the latest findings on four unique and fascinating artifacts. These tablets were originally discovered in a dig site under what has become known as Site 3.''

''Subsequent examination of the surrounding area and carbon dating of the tablets brought UAC researchers to the conclusion that the tablets belonged to a civilization that existed millennia ago and were placed in a holy burial ground of some sort. Utilizing the best minds in linguistics and UAC proprietary pattern recognition software, the tablets were exhaustively examined. What we found was fantastic.''

''The first tablet provided us with a wealth of scientific data. Specifically detailing the mathematical concepts behind teleportation. UAC researchers used this information as the cornerstone for building the Delta teleportation devices.''

''The second and third tablets illustrate and epic story. A story of war and how faced with impossible odds the ultimate sacrifice of an entire race to achieve victory.''

''The fourth tablet details how the essence of each individual was captured and placed into the artifact that we now refer to as the Soul Cube. This device was wielded by their mightiest warrior and with it he banished the invading horde forever.''

''Our researchers are still analyzing the recently found hidden section of the fourth stone and some related fragments. It goes into detail on the invading force and indicates the remaining survivors may have teleported somewhere. Where we do not know, although it seems to reference a map we have yet to locate. To date there remains no evidence of any type of invasion at any of the sites. Our assumption is that time has removed all but what we now see.''
