Possibbly the worst game I've ever played.
Navigation: Your only navigation tool is a paper map which you can't actually see while moving.
Driving: You have to drive about 20Km between every objective, there are guard posts every 100m down the road which respawn completely if you drive away for about ten seconds.
Difficulty: Idiotic. On the easiest difficulty the enemies can survive 20 bullets to the chest with an assault carbine. To stop this you must change it to the hardest difficulty in which nothing changes but the amount of ammo you can carry. Why would a mercanary go into the jungle with 2 clips and a grenade?
Repetetive: Every mission is the same; Drive 20Km to this base destroy or kill something drive back get paid, fight off 200 guard posts and patrols on the way there and do it all again.
Stupid limitations: There are giant invisible walls and mountains everywhere not to mention your character has malaria and has to go find some pills every 2 hours as to avoid dropping dead.
Combat: I've already mentioned bullet sponging. The grass is about 8 feet high so you can't see anyone.
