MAP25: Under the Horizon (10 Sectors)

MAP25: Under the Horizon is the twenty-fifth map of 10 Sectors. It was designed by Jonas "Chrozoron" Feragen and uses the music track " ".

Essentials
Get the shotgun from the boat and traverse across the nukage. Keep going once you reach solid ground (there is an armor and a super shotgun to the left if you need them), following the linear path until you end up at a docking bay. Head onto the boat first, and get inside to find the blue key. There is a megaarmor on the bow of the ship if you need it as well. Exit the ship and go back east, then south towards the light. The blue door is nearby, and in the room that follows is the blue key. From there, head back towards the entrance of the boat. A baron of Hell was guarding the red door here before, open it and find the switch inside. Then head back outside and west through the now open passageway.

When you reach the next area, you will have several enemies to tangle with. You need to get onto the raised walkway, and there are two switches to press to do that. The first is near the rocket launcher, and the other is behind a wall to the east. Go along the walkway afterwards and you should spot the yellow key. To get it, you can open a fence just east of it and flip the switch inside. After getting the key, open the yellow door ahead and you should find a plane. Press the switch near it to open the loading bay, then press the switch and the door to exit the map.

Other points of interest
There is a soul sphere on a ledge in the nukage river at the start. You might want to grab the radiation suit first, and then backtrack through the nukage river to get it, as it not only damages you, but slows you down too.
