almost old-school fps with a bit of half life/bioshock vibe
features:
- the weapons are pretty basic (exceptions being the rocket launcher, grenade launcher and the "seeker", which let you steer the projectiles)
- time mechanics are well done, you can age and objects and enemies at the press of a button (which boils down to an insta-kill for the small ones and slows down others) and also restore crates, bridges, stairs etc which makes for a few nice little puzzles (and also massive sequences when you "resurrect" a 50-year old destroyed bridge or freighter, for example)
- your time device also doubles as a more or less carbon copy of HL2's gravity gun
- upgrade system works kinda like bioshock
the story isn't epic, but it does its job and sets this game a bit apart from all the other "kill big bad guy and everything that stands between you and him" games. you basically spend the rest of the game fixing a honest mistake you made at the beginning
shooter mechanics work really well. it's raven, after all - they know their stuff.
enemies are diverse enough, requiring different tactics. the AI does its job, but more or less every battle is linear and scripted anyway.
no health regeneration! good old medipack system
gfx: good enough
sound: nothing to write home about, but not bad either
bottom line: not really a GOTY candidate, but it's a damn good rock solid FPS with a few nice touches
