The additional content from the PS3 version of Splinter Cell: Double Agent is now available to Xbox 360 owners on XBL Marketplace.
Two new multiplayer maps (Kinshasa and Secret base), four new challenges on those maps and a brand new character, the Spy Girl, plus three outfits are up for download at no extra cost.
Or alternatively you could just go back and play Chaos Theory, where the multiplayer mode hasn't been toned down for stealth-less monkeys (meow).
The next Xbox 360 exclusive instalment Splinter Cell: Conviction meanwhile, has been delayed until early next year. So it's probably good news if you can find six months of entertainment out of the Spy Girl and her outfits.
