The game's basic gameplay is the same as the original Painkiller. The player has to face off numerous enemies and defeats them, moving from one location to another. All the weapons have alternative fire regimes. While the majority of enemies and all original weapons are presented, the game features some new additional gameplay elements not seen in original or its other expansions.Go to: http://store.steampowered.com/ and download STEAM client
