This is a singleplayer/coop centered DLC, introducing new maps, a new boss fight, a new weapon, and a much deeper storyline (deeper in terms of wading through demon blood).
Features:
3 singleplayer/coop maps themed around picturesque ocean view settings: Monastery, Docks and Ruins.
New Ruins level with epic sea-monster boss fight.
Redesigned boss: check out the hellish offspring of Thor and Leviathan.
New enemies: Ancient Soldiers, Conquistadors, Gimps.
Revamped enemies from the original Painkiller: Hellbikers, Rocket-Jumpers, Scythe Monks, and Grenadier Monks.
New weapon: Cannon; Primary Fire: shoots a massive fiery cannonball that pushes enemies away, burning/insta-gibbing them on direct hit and at close range; Secondary Fire: shoots an icy cannonball that freezes multiple enemies on direct impact, and slows enemies in an AoE-radius.
New Tarot Card: 666 ammo.
