Mass Effect, one of the best games released last year for Microsoft’s Xbos 360, will be released for PC in May this year. The game, developed by BioWare, will be published by Electronic Arts.

Mass Effect is an epic science-fiction action and role-playing game (RPG) experience. During the game, the players assume the role of an elite human Spectre agent, Commander Shepard, entrusted with keeping law and order in the galaxy.

Shepard uncovers a threat so great it could destroy all life in the galaxy, but her job is complicated by the fact that no one will believe the word of a human, a race not fully trusted by the other alien races. However, the galaxy must be convinced of the grave threat at hand or all life could be exterminated.

The Xbox 360 version was released last year in November and it has sold already somewhere around 1.6 million copies.

However, the PC version will suffer some changes and EA has released a list of the aditionl features. Of course, Mass Effect for the PC will have optimized and fully customizable controls and highly detailed textures, characters and environments.

Also, EA promised a new feature called Run & Gun Control, which means the players can assign biotic powers or skills to ‘hot keys’ allowing them to play Mass Effect with a heavier focus on action, a new decryption mini-game and new inventory screen GUI and functionality.
