I hadn't played this game for a while, so I decided to take it off my shelf and try it out again for some achievements. Two seconds into the game I remembered why I quit, it's boring and there's no mercy from the AI. I fire one bullet and they ALL turn to me? ALL of them? I was hiding in a freakin' bush! They can shoot through leaves when there is obviously no way they could see me if they were real people, and there are like five guys shooting me with submachine guns from 50 metres away at the same time. Top it all off with a super small supply of ammo and crappy allies. I've beaten the Call of Duty 4 campaign on Veteran, and completed a few Call of Duty 3 missions on Veteran, not to mention I'm pretty good at Halo too, but this FPS just drives me insane. The funny thing is, is the fact that I was playing on Normal. NORMAL. I really have to work hard for these achievements, and man, achievements they are.
