Game Description

Valve's quirky puzzle game is getting a new lease on life with Portal: Still Alive, a sequel/expansion for the original game. Portal: Still Alive will be an Xbox 360 exclusive game offered for download over Xbox Live Arcade. It's expected to release in late 2008. Originally included as part of The Orange Box -- a Valve-developed game bundle including Half-Life Episode II and Team Fortress II -- Portal stood out as one of the most unique games of 2007. Players guide an experiment subject through an increasingly difficult series of mazes and obstacles. The goal is to navigate to the end of the game through clever use of your Portal Generator -- a gun that literally shoots portals. By cleverly exploiting space and physics, players can build up to incredible speeds to jump gaps, bounce from wall to ceiling, or avoid and trick enemy gun turrets.
