Great idea that did work.
The bad about the game is Graphics, though they are O.K the and not smooth and flowing, very sharp and sometimes glichy, but still good enough to keep things realistic. Overall they should have been better.
The partnership is great and works increadibly well, specialy when you die you can switch to your partner and save yourself. and also have a broader range of fire power as both use different weaponry.
The levels are not linier and change dramaticaly, giving a huge range of tactical changes and environments. AI is very good too, suprisingly good, they run around and shoot when they see you and stop when they dont.
some parts where difficalt and almost became frustrating but never to the extent of finding the game agrivating.
I like and enjoyed this game very much so and would deffinantly recomend it to FPS fans. and you can pick it up cheap now!!
