Uncharted 3's multiplayer mode, which recently went completely free-to-play for PS3 owners, is getting some new DLC in recognition of April's "Prevention of Cruelty to Animals." Naughty Dog's Pogo and Trumpet are being featured as DLC on custom t-shirts and weapons, with all proceeds from the sales going to a charity that supports the prevention of cruelty to animals.
The items are currently available in North America individually and as a bundle, and will go on sale later in the month for all other regions. Remember, only April is "Prevention of Cruelty to Animals" month (although you should never abuse an innocent animal), and because of that the items are only available for limited time.
The full list of all the Animal theme parts on sale is outlined on the Uncharted 3 Multiplayer free-to-play page.
