However, the countdown can be reset by grabbing large air bubbles as they emerge from the ground. Other hazards include collasping ruins, waterslides, and underwater currents. In addition, there are puzzles involving pushable stone gargoyles, which often led to rewards. The boss here emerges from one of five chutes and tries to shoot the player. If the player falls into the water below, they'll be electrified a short time later. After six hits, the entire arena is filled with water, making the fight difficult to complete without the use of air bubbles.

Revision as of 15:47, 17 December 2014

Sonic Robo Blast 2 (or SRB2 for short) is a fan made, free Sonic-themed game using a modified version of the Doom engine, based on Doom Legacy. The game focuses on recreating the feel of the classic games, as opposed to the newer Sonic that Sega has been making games for now. So far, the current beta release version is version 2.1.12. It is not yet complete, as some acts of zones are missing, and Dark City is only at the conceptual stage.

Engine

While the engine is derived from Doom Legacy, which was originally chosen for its 3D floors, it has greatly diverged and been extended in different directions.

  • The original Doom games are no longer supported. FraggleScript has been removed as well.
  • New 3D floor effects, such as intangibility in one direction, or crumbling a few seconds after a player lands on them, among others
  • Polyobjects with additional effects allowing to create moving platforms, though they are still subject to the original rendering limitations
  • ANIMDEFS
  • Lua scripting
  • Custom "SOC" ("Sonic Object Configuration) content definition language
  • Partial support for ZDoom's TEXTURES lump
  • Camera effects
  • Skins extended to full-fledged character classes

Gameplay

In SRB2, players run at high speeds through generally light-hearted, happy levels (though some exceptions do exist, such as the Castle Eggman Zone), in comparison to the usually dark and dim battlefields of Doom levels. Players jump heights unprecedented in Doom, achieving heights of 124 fracunits. Players are additionally equipped with a spindash, which can be charged up using a spin button. Also, players encounter badniks in the field, that can be destroyed by jumping on them once, as opposed to the hellspawn of Doom which require several shots to be slaughtered. After two acts of gameplay, players encounter a third act of gameplay in which they find a boss, who must be completed to finish the level. In boss acts, an egg capsule rises out of the ground for the player to jump on, and finish the act. However, not all boss acts feature an egg capsule, and end the level shortly after defeated. The most current version of Sonic Robo Blast 2 has six different zones, some still not yet complete.

At the character select screen, players choose between one of three characters: Sonic, Tails, or Knuckles. While Tails and Knuckles have mid-air abilities that resemble their previous appearances (Flying and Climbing, respectively), Sonic has an ability not seen in previous Sonic games: the thok. When Sonic thoks, he shoots forward at high enough speeds to pass through one-sided linedefs. (Map designers have reacted by inventing the Thok Barrier, a dummy sector of height 0 which completely surrounds a level, permitting the boundary walls to be two-sided.) This gives Sonic a massive advantage in multiplayer modes such as race, and also in the single-player time attack.

Another feature of SRB2, special stages are included for the player to collect chaos emeralds. When the player finds an emerald token in the field, they will be taken to a special stage. In side a special stage, the player must collect a specified amount of rings. If the player succeeds, he will obtain a chaos emerald. Featured in the special stages are hazards such as time-draining water, lava that removes 10 rings, and other obstacles.

After collecting all the chaos emeralds, Sonic obtains the ability to turn into Super Sonic. Players turn into their super form by doing their mid-air action with 50 rings and no shield. When the player is in his Super form, he can jump higher than before, as well as run faster, and on water. Sonic has the ability to float in mid-air when the player presses and holds the spin button in air. While in Super Form, the player is constantly drained of rings. After the player loses all of their rings, the player turns back into their normal state, with normal jump height, speed, and loses the ability to run on water and float.

Levels

Here are the levels current as of v2.1

Single-Player

Greenflower Zone - A grassy area filled with rivers, small trees, and flowers. Act 1 is a rather short level which introduces the player to the basics of the game. Act 2 takes place at the bottom of large canyons, and also features large rivers, waterfalls, and caves. The boss of Greenflower Zone simply fires a laser that tracks towards the player. After 5 hits, he will instead spawn spikeballs that rotate around him and charge at the player.

Techno Hill Zone - Eggman's presence in this area has altered the landscape. Most noticeably, he's filled low lying areas with dangerous slime, which the player must take care not to fall into. Act 1 takes place outside and in the entrance to one of Eggman's factories. Act 2 takes place in the heart of the factory and has lasers, conveyor belts, crushers and turrents. The boss flies in a circular pattern while spewing small puddles of slime. After 5 hits, the boss bounces at the player and spews slime into a circular pattern with each bounce, and attempts to mariostomp the player.

Deep Sea Zone - As the name would imply, this zone is set largely underwater. Remain there for 15 seconds, and the player will down. However, the countdown can be reset by grabbing large air bubbles as they emerge from the ground. Other hazards include collasping ruins, waterslides, and underwater currents. In addition, there are puzzles involving pushable stone gargoyles, which often led to rewards. The boss here emerges from one of five chutes and tries to shoot the player. If the player falls into the water below, they'll be electrified a short time later. After 5 hits, invulnerable, inflatable eggman clones will appear and start emerging from the chutes simultaneously, and will shoot at you along with the original.

Castle Eggman Zone - Takes place in the rather gloomy mideval fortress under Eggman's care. Swings will propel you ahead and above, but watch out for swirling maces, cannonballs, and flamethrowers. Act 1 takes place in the forests and gardens on the property, while Act 2 covers the chambers and grounds of the titular castle. Its boss has a 3D-floor based cage that it uses to protect itself while swinging around long strings of maces to hit you.

Arid Canyon Zone - This rather scenic and rugged canyon is accented with cacti, tumbleweeds and the occasional oasis. Moving cables will give you a lift over precarious ground. Jump quickly to escape quicksand and pools of oil. Watch out for rockslides, open fissures, and slippery oil slicks. Arid Canyon Zone has one act and no boss.

Red Volcano Zone - The lava in this expansive subterrian cavern is prone to rising without warning, so watch out. Other things to be wary of include series of collapsing platforms and jumping fireballs. Red Volcano Zone has one act and no boss.

Egg Rock Zone - The player finally makes it to Eggman's extraterrestrial headquarters planted firmly on the energy-filled Black Rock. This zone features many of the previous levels' hazards and gimmicks, and adds inverted gravity (which can be triggered by the player sometimes, and sometimes not), air locks, and short romps through airless vacuums. Remain oxygen-free for too long, and you'll suffocate. Act 2 is also features brief 2D sections. Egg rock zone's boss acts include a race and fight with Metal sonic, and a brak eggman fight based loosely on the cyberdemon and archville.

Neo Aerial Garden Zone - A hidden level set on a picturesque floating temple. The name of the game here is risky platforming over an unforgiveable and vast bottomless pit. Activate panels (some of which must be warped to) to open doors and progress further. Neo Aerial Garden Zone has one long act and no boss.

Mario Koopa Blast Zone - A tribute to the original Super Mario Brothers, with 8-bit Goombas, Koopa shells, coins, and item-filled boxes. Act 1 takes place (mostly) in the overworld and through systems of pipes. Act 2 is a rough recreation of World 1-2. Act 3 is a dangerous excursion through Bowser's Castle, with no coins (rings) and slamming Thromps. Mario Koopa Blast Zone has no boss.

Spring Hill Zone - A delightfully abstact landscape with reduced gravity. The main attraction here is Super Sonic. Touch him and you'll be set along a 2D-oriented flight path a la NiGHTS into Dreams..., with the ability to paraloop objects, rings and enemies, and drill dash to boost ahead. Spring Hill Zone has one act and no boss.

SRB1 Remake - A remake of the original Sonic Robo Blast using new graphics, but orginal enemy sprites and music. Bosses are not yet playable, and not all of the levels have been remade.

Later editions of Sonic Robo Blast 2 will feature additional levels, bosses, and other content.

Multiplayer

SRB2 supports numerous multiplayer modes, some of them sporting first-person gameplay, while others featuring more Sonic-like gameplay.

Co-op

SRB2 supports a Cooperative mode, in which many players can complete a level together. The levels proceed normally, and after one player completes the level, the stage ends.

Competition

This mode is a variation of Sonic 2's split-screen mode. There are five different requirements: score, time, ring count upon finishing the map, total number of collected rings and number of popped monitors. Players receive points based on how well they were in each of the five categories (e.g. the player with the most total number of collected rings receives points equal to the number of players currently playing). The winner is based upon who has the most overall points at the end of the level.

Race

In this mode the winner is based upon who finishes first, or Time is the only factor counted for the winner, as opposed to the points system installed in Competition. 60 seconds after the first player finishes, all players that have not finished run out of time and die. As for completing the levels, two systems exist: normal and circuit. The first type of racing is much like co-op: the first one to finish wins. The other type, circuit, requires the player to finish a number of laps around a course. The number of laps is specified by the server.

Match

Players chuck rings at each other. Rings draw ammo from the player's ring count, and thus the player must conserve ammunition. Also, an interesting twist is that a player loses all of his rings (which are also ammo) after being hit. The player is given invincible time to collect spilled rings, or just plain rings. When the match ends, the player with the most points wins. As of version 2.0, a new Match system has been coded, along with Tails and Knuckles' super form, only available in Match or CTF.

Tag

Players either shoot rings at each other, or touch each other to pass on the "it" status, depending on whether Tails pickup ON or OFF. Characters who are not "it" lose their special jumping ability in order to give the person who is "it" a fair advantage. Points are earned if one player can avoid being tagged if the "it" status is given to another player.

Capture the flag

In Capture the Flag, players attempt to capture the opponent team's flag. Players choose teams by jumping on the team base that they choose. Afterwards, players must try to capture the flag. The both flags must be at base to score a point. Also notable, the player loses use of his mid-air ability when carrying the flag.

How to load add-ons

New characters and levels can be added by entering the console (by pressing the key ¬ or `) and typing the following without the quotes: "ADDFILE NAME.WAD". Then simply press enter to execute the command, or add the WADs via the Launcher by going to the WAD files section and adding them there.
