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.
A level expansion for Portal was later released in 2008 as 
Portal: Still Alive, which included new maps based on maps from the Portal: The Flash Version MapPack, which was an unofficial Portal mod with maps replicating Portal: The Flash Version in real Portal. These Portal: Still Alive levels would later be unofficially ported to the PC in mod form, and later would reappear in the Portal Companion Collection for the 
Nintendo Switch.
In 2022, Nvidia released Portal with RTX, a remastered version of Portal developed by NVIDIA Lightspeed Studios (who also co-developed Portal Companion Collection for Nintendo Switch, and previously ported Portal to NVIDIA Shield devices) which takes advantage of newer hardware and adds ray-tracing support, PBR textures, new high-poly models and much more.
