Sex appeal...
I recently played this game and just completed and i thought the graphics arnt the best the source engine can do however they were working with a beta version at the time of making. They do look sharp however and the artwork is really great, it's a sexy game and the storyline + the women really draw you in.
What kept me playing though was this girl in her school uniform styled outfit and blonde hair, i wanted to see more of her. Sadly however i didn't see as much as i liked and as its a game there isn't the freedom of real life lol. For some reason the game reminded me of Max Payne in a way, not the actual gameplay but the settings and the jokes + the general things put around the map that you can play with.
The only thing that lets this game down really is the combat system like everyone says, i wasn't a fan of having to switch from first person view to third for combat and the general feel of combat was bad such as controls. There seems to be a inbalance of weapons too i found that a gun too like 10 shots to kill a human where as a punch or two would kill them :\ There also seems to be ALOT of bugs in the game.
The sounds are all there and really good and i picked the game up for £5 so the value + replability is all there. No multiplayer but tbh you wouldn't expect one. The game will last quite awhile, i played for about 20 hours and for the price thats great!
End of the day it's a great game with some downfalls. I really wish'd they improved the combat system and oh i forgot the AI is TERRIBLE. However the rest of the game is GREAT and most importantly i had fun.
