I'm not sure why the spelling "alfa" is used. Anyone know what country Frigidman hails from?
You get dropped off in an underground complex, given more long-winded but vague instructions, and set loose in a network of corridors lined with some neat polygon work. Most of the enemies here are fighters, but I still ran out of desired ammo a few times. The exploration is less annoying than on the previous level since all the switches are in plain sight, but you'll still go all over the level looking for changes.
This level has a few interesting tricks up its sleeve. Near the end, you'll encounter a working airlock, which I believe had never been done before. The elevator to the east is a "real" elevator, but it's a total fake: The walls move but the floor and ceiling don't, and the two floors are at the same level. The moving doors are done with a set of very thin platforms, to enhance the illusion. The final puzzle, the destruction of the computer core, is a very nice puzzle involving careful observation of a large number of circuits to smash.
On to the B'rak Power Station...
