While I find the still $19.99 price tag a bit much for a 7 year old game I still found this very enjoyable.
The game is very much like the Half Life series as it blends puzzles in with action and genuinely tried something innovative with the time control mechanics which work very well.
The graphics are pretty good although the environments cna look very bland. Lots of flat textures and the colors are mostly grey. The story itself is very much like Half Life 2 as there is a dystopian future (or past as it is in this game) that is ruled over by a tyrant who loves to talk about himself over large jumbo trons. The voice acting isn't bad but it's nothing to write home about. It doesn't get in the way but there's never a moment where I went "Oh wow what a great line!"
The weapons are all varied and pretty damn fun to use. The action in the game really feels like one of those games nowadays that tries to capture that "old-school" shooter vibe and yet the game just plays it straight intead of trying to shove it down my throat. When I slow down time then unload both barrels of my shotgun on a guy and I watch as his ragdoll flies backward while still in slow motion as his blood splatters on my screen I know it was badass I don't need a game (or game's character) to TELL me I'm badass.
This is the only purely action time manipulation game I can think of other than maybe Singularity although it's not really the same manipulation. Not many games allow me to reverse time and walk past the guys who just kicked the door down in front of me and unkick the door down in reverse time so that when I bring time back I was behind them the whole time with shotgun aimed squarely at their backs.
Is it the best game ever? No. It's weak story and bland environments really bring the game down and you'll find yourself not caring about any of the stories or characters and Dr. Krone does not make for a good villian especially when you barely here him speak other than on some jumbo trons while loud gunfire is happening. To bring up Half Life again, Dr. Breen was such a good villian because his face was everywhere constantly preaching the combine's message as he has sold out humainty so that he can live in comfort. Behind all of his messages and threats he is just a coward sitting up in a tower. You really get to hate the guy. Dr. Krone is just evil scientist number 7 that wants to rule the world becasue...EVIL.
If you are looking for an action packed old school style shooting game however this is the game for you. How many games let you pause time, take an enemy's weapon, stick said enemy with a grenade, then use his gun to headshot his buddy he was talking to? Tell me please because if there was I'd be playing that game too.
