The latest part of Ubisoft's Far Cry 3 survival video series is here, and like the others, gives you a good idea of what you're going up against. It being the jungle and all, you can expect to fight everything from mercenaries to leopards to sharks.
Outside of that, gameplay seems to resemble Crytek's early work more than Crytek's current work (despite this being developed by Ubi), and graphics are damn impressive, though the art design is a little too cartoony my tastes. See for yourself:
Far Cry 3 launches December 4 on PC and consoles.
