SEGA's first lump of downloadable Aliens vs. Predator content will be released on 18th March.
This Swarm Map Pack will cost 540 Microsoft Points (£4.60/€6.30) on Xbox 360 or £4.79/€5.99 on PS3. SEGA has told us the Steam price will be £4.79.
Inside are the four maps offered for free to Special Edition AVP buyers. Two of the maps - Docks, Machine - work across all six competitive multiplayer modes. The remaining two - Outpost, Hive - are maps for the wave-based co-op mode Survivor.
Aliens vs. Predator finished third in the UK All-Formats Chart yesterday, three weeks after release. Only newcomers Battlefield: Bad Company 2 and Heavy Rain - plus Ubisoft's best-selling Wii game Just Dance - have displaced AVP.
That's a strong finish for a game with a solid albeit unremarkable critical reception.
