Has deep, captivating storyline, amazing graphics that leave Crysis and other modern games in shame. Shadows? Who needs them, we have (gouraud-shaded) dynamic lighting! Lack of detail in enemies? WE HAVE MORE OF THEM! This game totally takes everything out of the original Unreal Engine.

Extraordinary quality of the voice acting comes apparent when you are millionth time nagged that you are doing something wrong and you must go somewhere, and it still doesn't sound annoying. At all!

Static AI makes aliens fun to fight against, no pesky dynamic situational goal-based AI or anything else here!

Level design is totally out of this world, and although the game has only three bonus stages(which you can enter every time you finish a level, which you'll be doing alot) they won't get repertive due to very dynamic nature of the levels.

Clearly the best game that has ever been made.
