Mass Effect 2 is an action role-playing video game developed by BioWare and published by Microsoft Game Studios and Electronic Arts for Windows and Xbox 360 in 2010 and published by Electronic Arts for PlayStation 3 in 2011. It is the second installment in the Mass Effect series and a sequel to the original Mass Effect. The game takes place within the Milky Way galaxy during the 22nd century, where humanity is threatened by an insectoid alien race known as the Collectors. The player assumes the role of Commander Shepard, an elite human soldier who must assemble and gain the loyalty of a diverse team to stop the Collectors in a suicide mission. Using a completed saved game of its predecessor, the player can impact the game's story in numerous ways.
In combat, the player can pause the action to calmly target enemies and select different powers for the squad members. The enemy's life bars are shown in a frame at the top of the screen.
