The Mediterranean Traveller Map Pack for Assassin's Creed: Revelations will be available to download on 24th January, Ubisoft has announced.
It costs £7.99 on PlayStation 3 and PC, or 800 Microsoft Points on Xbox 360.
The Mediterranean Traveller Map Pack gives access to six additional maps for the game's Abstergo-based multiplayer modes - three new, and three recycled from Assassin's Creed: Brotherhood.
Fresh locations include Jerusalem, Dyers and the imperial district of Revelations' setting Constantinople.
Players can also revisit Brotherhood maps Firenze (Florence), San Donato and night-time Siena.
The Mediterranean Traveller Map Pack is the second slice of multiplayer DLC for Assassin's Creed: Revelations after previous helping The Ancestors Character Pack.
It launched last month and added four extra personas to the online stabathon, along with a sprinkling of new Achievements/Trophies.
