Angel (Exodus)

This is on the verge between being frustrating and entertaining. It pulls a lot of dirty tricks - right at the beginning you teleport into some imps, and unless you're expecting it the ones behind you knock off some of your health - and the traps become predictable. And I don't like spectres in dark areas, it's cheap. But the ammo balance is pleasing and it's one of those maps where it's fun to dodge around the enemies, letting them fight each other.

Very atmospheric level, vaguely resembles some kind of a medieval castle in space. Pretty much no filler encounters, almost every fight is very dangerous and there are many deadly traps. Play if you're ready to die a few times and don't mind some trial-and-error gameplay.
