Story-wise, Ubisoft is keen to keep the all-new Wii tale under wraps, but it's safe to assume that Carver will have his feral abilities from the beginning of the game - and you'll meet a new character called Kien Do, who's the government's "chief lieutenant, bodyguard, assassin... unofficial army commander, police force, judge, jury and executioner." Probably a pushover.
There'll be four-player multiplayer, too. And Ubisoft says there's a possibility of downloadable content, as with the Xbox Far Cry, turning an already roasting FPS into a roasting FPS with increased longevity. Your trip to paradise begins in November. Bring a gun.
