You may remember a few weeks ago
that Ubisoft laid out a challenge for the Assassin's Creed: Brotherhood (Xbox 360)
community. The challenge was to amass 25 million total kills.
Well all your hard work seems to have paid off, as on Gabriel Graziani's twitter this morning he announced that the community challenge had been completed! The new map is entitled Rome at Dusk
, a variant of the Rome map that came with the game. Note that you do not need to download anything, as the map shows up on the map selection screen and is part of the rotation on multiplayer.
