Want to go into a mercenary camp quietly, hacking soldiers apart with your machete? That's viable, as is sniping enemies from afar, or rolling into the camp with a jeep, running over as many enemies as possible before the bullets fly. stunning but the openness of every level gave you plenty of tactical room to work with when you squared off against them.
Not only was the non-scripted, unpredictable enemy A.I. Essentially a sandbox version of Half-Life, Far Cry blew everyone's minds back in the day. The first game focused on a soldier named Jack Carver as he searches for a journalist on a mysterious island filled with mercenaries and bloodthirsty mutants born from evil experiments. The original Far Cry game, developed by Crytek and published by Ubisoft, is radically different than what the series is today.
