The multiplayer component of Crysis Warhead, Crysis Wars will be free to play for a period of days from Friday, the 19th of December to the 28th of December 2008.

Crysis Wars is also set to get some new content in the form of a map pack (that by the way will be included in the free trial). Here’s the lowdown on the 2 new maps, courtesy of gametactics.com :
Savanna (PowerStruggle): The large Savanna plains in the neighborhood of the Victoria falls provide ideal maneuvering grounds for heavy armored vehicles. The North Korean army has found out about this training facility and launched an attack on the US forces.
Nash, as he prefers being called, woke up to the wonders of gaming rather late but don't bring that up around him. It's a touchy subject. A self confessed Battlefield veteran, Nash spent a good part of 2010 on the Steam Battlefield - with Bad Company (see what we did there?). He has a zero tolerance policy towards RTS games but is currently showing an interest by picking up and moving people - who he refers to as units - in the office. Thank God he's not that enthusiastic about Angry Birds or we'd be seeing women flying all over the place. Bali... Bali, put the receptionist down now.
