This game is included in the following packages:

• The Orange Box
• Valve Complete Pack

Portal (2007) is a puzzle video game using the Orange Box engine. Taking place in the mysterious Aperture laboratories, the game operates as a puzzle-based shooter, allowing you to create portals that link to one another on any flat and large enough surface.

The gameplay is similar to Narbacular Drop by Nuclear Monkey Software, an indie game that won the IGF 2006 Student Showcase. Members of the development team who created the game were hired by Valve in 2005.
