Where to begin....
Terrible plot, uninteresting antagonist, horrible voice acting, uninspired weapons, the list goes on. One of the BIGGEST faults, however, was it's claim to be an open-world shooter. This is fine until you realize that you can only ever drive on roads, and 90% of those roads are blocked on both sides by impassable mountains.
Enemies respawn ridiculously quickly, are boring to fight, shoot you from a mile away and never, ever give up chasing you. Also; they are immediately aggressive, which is just odd considering the game puts you as an 'outsider'. Having to dig shrapnel out of yourself to prevent death is also bloody annoying. As is having to find malaria pills to also prevent random dying.
The buddy system, whilst having the potential to be very interesting, is completely devoid of anything substantial and could be completely omitted without it affecting the gameplay one bit.
The less said about the ending the better.
And to top it all off, there are the aforementioned colonies of bugs that inhabit the game.
Absolutely dreadful game. I've never quite forgiven PC Gamer UK for giving it a 94% score, when it should really have been down in the 45-50% range.

PS I dd TRY and play this game; I installed it and ground through 3 hours of it before I finally gave up and purged this horrific piece of software off of my hard drive. Worst game of 2008.
