Far Cry 2

Caught between two rival factions in war-torn Africa, you are sent to take out "The Jackal", a mysterious character who has rekindled the conflict between the warlords, jeopardizing thousands of lives. In order to fulfil your mission you will have to play the factions against each other, identify and exploit their weaknesses, and neutralise their superior numbers and firepower with surprise, subversion, cunning and, of course, brute force.
