Online RISK game lets Facebook users conquer world

US videogame superpower Electronic Arts is sending Facebook members out to conquer the world with a humor-infused version of the classic strategy board game RISK. The game -- in which players march across the globe and seize territory with the goal of world domination -- has been re-designed for Facebook, with on-screen characters including zombies, cats, donkey cannons, and mermaids. "RISK: Factions for Facebook" is based on versions of the game released in 2010 for play at Microsoft Xbox Live and Sony PlayStation Network, two online entertainment services. "Fans of the classic game will find familiar features such as dice-based combat, iconic maps, and the player turn sequence of reinforcing troops, attacking and fortifying territories," EA said in a statement.
