Role-playing action title Alpha Protocol goes on sale for the PC, Playstation 3 and Xbox 360 June 1, Sega announced this morning.

Obsidian Entertainment's modern-day role-playing game has players taking on the role of spy Michael Thorton as he tried to uncover who was behind the missile attack on a passenger plane.

Gamers that pre-order Alpha Protocol through GameStop will receive the Exclusive Assault Pack, containing exclusive weapons and ammo like the UC Regulator high damage shotgun and Rittergroupen Grizzly high accuracy rifle.

I'll be interested to see how this game compares to Mass Effect 2's blending of action, shooter and RPG.
