Though Far Cry 2's enormous map entertains movement in any direction, you're strictly set on a path of violence. But the world's organic nature can't be escaped, with even minor firefights threatening to set off spectacular chain reactions. Whether those play in your favor largely depends on your ability to deal with unreliable weapons, misfiring rockets and ravenous fires. It's a thing of beauty when your perfect plan degenerates to, "Right, I'm going to burn everything to the ground."
Be careful, though -- it's easy to get burned yourself. As your missions for Africa's duplicitous dictators become more lucrative and increasingly despicable, you may be surprised to find how easily your morals crumble under the weight of progress. Joseph Conrad would approve ... but he'd probably complain about the rapidly respawning guard checkpoints a little bit.
