Just Cause 2 is an open world action-adventure game and employs the Avalanche Engine 2.0, an updated version of the engine used in the original Just Cause game. Just like the original the game is set on the fictional island of Panau, only on the other side of the island from the original.
Panau has varied terrain, from desert to alpine to rainforest. Players are free to roam the game's open world, not having to focus on the game's storyline.
