Yes, Max Payne 3 was just released hours ago and yes this is Day One DLC, but in this one case it is acceptable because it is free. The Gorilla Warfare Loadout Pack gives you three items that will give you bonus in-game.
The items are as follows:
- The Gorilla Mask gives you extra adrenaline for melee kills from behind.
- The Lucky Coin gives you extra cash from looted bodies
- The Booby Trap makes your corpse booby trapped so that it explodes when looted by another player.
