I really enjoyed my time with this game, though I can't help but feel a little let down in some ways. The first few missions are an absolute treat, with so much variation in gameplay and locations that give you multiple weapon choices, all placed perfectly to give you a completely different mission feel experience upon replay. There is a lot of intrigue, and the combat is simple yet satisfying.

However, the second half of the game becomes very repetitive, and a bit of a slog. The level design suffers greatly, and becomes a confusing maze. This is not helped by some frustrating checkpoint mechanics, where if you get unlucky with a bad checkpoint, you can end up walking through the same hallways before getting back to some forward momentum. The exception of this is the final level, which is an absolute treat. It does the perfect job of making you feel like the main character in an action movie, and it does make up for some of the frustration of some of the previous levels.

The story is simple, straightforward, and functional. The gunplay is satisfying, with each gun feeling very different with it's own advantages and disadvantages - and the atmosphere is great, especially on the level where you first encounter the flood. I can't see myself replaying this again, but it was definitely fun to run through the once.
