I installed this one about two weeks ago, but I haven’t been playing it much. I don’t know why, because the game is excellent. I played almost the entire day yesterday and got the story 22% complete. I also completed a bunch of side quests, and finally got a new stash of malaria pills. One of my buddies is now missing in action, sadly. I didn’t notice he was in trouble, so by the time I realized it, he was already gone. I don’t know if he comes back after a while, so I’m doing missions for other buddies, including the one I saved recently. I will try to play some more today.
EDIT: I’ve completed 42 percent of the story and got to a whole new area of the game which is, as far as I can tell, as big as the first one. I lost all of my buddies in a gunfight, but I think that’s how it was supposed to happen. The leaders of both factions are now dead, so I’m not really sure what will happen next.
