If your into busted graphics, bad clipping, frame rate issues, and using the same old guns found in every FPS go for it!
The AI was running into walls and at some points due to the already mentioned bad clipping through walls. The weapons are frankly all meh and there's not a single unique gun in the lot and the only gimmick the game tries to pass off that of being able to swtich characters may as well just be a switch weapon button becuase that's all it boils down to.
Everytime you swtich characters the former stands around like a braindead zombie only vaugely shambling behind you and making a comment now and then with voice acting so bad I have to ask if they just got some fast food worker to call it on for 20 bucks.
Seriously I could go on but just stay the heck away from this game. It's just awful all around even if it were released 8 years ago.
