Ubisoft has released another tidy trailer for Far Cry 3, the upcoming first person shooter sequel, set to return players to the tropical environments that the series was originally known for.

For some reason today's video is being referred to by Ubisoft as the "first gameplay trailer", which is odd because we've already seen a bunch of gameplay, but this latest clip does indeed feature more in-game action.

Check out the action-packed shooter gameplay and immersive world of Far Cry 3 through the troubled eyes of Dr. Earnhardt, the island's resident "pharmacist." Use an arsenal of weapons, explosives and vehicles to fight against the island's ruthless and deranged inhabitants. Explore a stunning and treacherous environment, filled with diverse terrain, exotic creatures and mind-bending botanicals.

Far Cry 3. Far From Safe. Far From Sane.

More than anything else, let's just hope that the game's implied use of hallucinogenic drugs doesn't put it on the bad side of the Australian Classification Board. Games such as Blitz: The League and Fallout 3 were Refused Classification because of drug-use with a perceived benefit to the player, although in those cases Steroids and Morphine have real-world equivalents. Perhaps magic beans won't bother. Watch the embedded video below.

Far Cry 3 is due on PC, Xbox 360 and PlayStation 3 on September 6th 2012.
