This is a level for unreal tournament based on concept art I made half a year ago.
If you are interested in following my progress or want to test the level yourself you can visit the forum thread:

The setting is a nuclear missile base on an arctic volcano that has been deserted by its inhabitants. It tries to imitate soviet era style, has been half destroyed by lava, and has a railgun on top.
