From Eidos Interactive:
...Each of the four maps features its own unique scenario: take on the local dope dealers and the Russian mafia at an LA construction site in Clean Cut, clash with the Yakuza in Tokyo in Hookers Trail, raid a drug barons mansion in a Venezuelan jungle in Flying High and ambush General Fuentes military convoy in the streets of Havana to steal the gold hidden in his vehicles in Hasta La Vista.
With Fragile Alliance we set out to offer gamers a new experience in co-op multiplayer, giving players the choice to work as a team or backstab their teammates and work for themselves at any moment, said Kim Krogh, Lead Game Designer, IO Interactive. The response to Fragile Alliance has been fantastic and these new maps will serve to grow the Fragile Alliance online community even further.
Fragile Alliance is based on greed, betrayal and revenge. Up to eight players team up against police or various enemies in a series of gripping heist scenarios - from here the choice is entirely up to the individual player. The objective is to steal the bounty and make it to a getaway point. The winner is the player who escapes with the most loot. How and when you make your move is up to you. So do you share the loot with your teammates or gun them down and keep it all for yourself?
Kane & Lynch seems like it is definitley worth checking out, and free maps are never a bad thing! If you own it, be sure to grab your's.
