N/A
Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original 
Portal over 70 industry accolades and created a cult following.
The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally-murderous computer companion who guided them through the original game.
The game’s two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters. This new mode forces players to reconsider everything they thought they knew about portals. Success will require them to not just act cooperatively but also think cooperatively.
Note:Portal 2 grants access to the Source SDK and SDK Base games. Its store page does not mention this.Contents
Features
Portal 2 engine branch introduces:
- Improved shadow mapping
- The entity
env_projectedtextureis significantly improved. Compared to previous implementations, it has higher default resolution, better edge filtering and support for the caching of shadows from static objects. - Video playback on materials
- Added support to render Bink Video in-game on surfaces, used for elevator screens in Portal 2.
- Blob particles
- A particle renderer that renders blobs of liquid, used for paint gel in Portal 2. A similar blob particles system are originally present in Source 2007 or Source 2009, but was disabled in code.
- World portals
- World portals that can seamlessly link together separate parts of the world. This feature is exclusive to this engine branch.
- Sound operators
- For defining complex audio behaviour.
- Finished water debris flow
- The base texture water flow feature from the Alien Swarm engine branch has been finished, with flowed normals now distorting color lookup and the flow map's alpha channel controlling color map opacity.
PS3 exclusive features
- Official PS3 Support
- When it comes to PS3, unlike The Orange Box, Portal 2 has been properly optimized for the PlayStation 3 as Valve takes advantages of SPEs cores on the RSX processor in the PS3, allowing for better performance. The PS3 version of Portal 2 (and CS:GO) are also integrated with Steam (Steamworks). Of little use to modders, needless to say.
- MLAA anti-aliasing
- Post-processing effect used to reduce stair-step (aliasing) effect on geometry and transparent textures, while having less performance impact compared to MSAA.
- Steam integration (Steamworks)
- PlayStation 3 version of Portal 2 features Steam integration. Achievements are synced with both PSN and Steam, and PS3 users were able to complete co-op levels with Steam friends. Steam services on PS3 have been shut down in May 2018, after support was dropped in 2016.
- PlayStation Move support
- Portal 2 on PS3 supports PlayStation Move motion controller.

Note:* - This game previously used to support Windows XP & Vista, however support for Steam for these operating systems has been dropped as of 2019, and with Portal 2 having the Steam API later updated in 2021, thus these operating systems are automatically no longer supported from running Portal 2. Additionally, Windows 7 and 8, 8.1 support for both Portal 2 and Steam has been dropped in 2024, which may cause the game to not launch correctly if the Steam API was updated and made incompatible for these operating systems.External links
