Far Cry 3 starts off with the kind of American frathouse holiday stuff - too much joyful irresponsibility - that is a turn-off for tall-poppy slashers like us, so there might be a "well, good job then" feeling when the tour party is kidnapped during their tropical getaway by a violent gang of locals.
It doesn't seem like such a good job when we learn what becomes of the unlucky travellers.
The pirates of Rook Island are represented by a chap named Vaas, who is completely unhinged and terribly violent.
You are Jason Brody, a spoilt American rich kid with no apparent aptitude for combat or survival, but your brother - and cellmate while Vaas unloads taunt after taunt - happens to be a former soldier, so maybe there's something in the genes.
As you go it alone on the island in search of friends, Jason will develop hunting and survival skills, and he'll grow into the bloodletting in a way that's thrilling - and unsettling.
