Warnings

The macOS (OS X) version of this game does not work on macOS Catalina (version 10.15) or later due to the removal of support for 32-bit-only apps.

Portal 2 is a singleplayer and multiplayer first-person platform and puzzle game in the Portal series.

General information

Steam Community Discussions

Steam Workshop for Portal 2

Availability

Source	DRM	Notes	Keys	OS
Retail
Steam		Portal Bundle also available.

All versions require Steam DRM.

Soundtrack is available for free as DLC and on the official website.

Owners of the PlayStation 3 version were previously able to redeem a single-use product key for Steam as well as link their game to a Steam account, which allowed cross-platform multiplayer with Steam players, access to your Steam friend list (chat, invites, etc.), Steam Achievements, and Steam Cloud save-games (PlayStation 3 saves are not compatible with other versions). However, Valve dropped support for PlayStation 3 in 2016 and shutdown the servers without warning on May 22, 2018.^[1]

Monetization

Type	Notes
Cross-game bonus	7 specific hats obtainable in Team Fortress 2^[2] can (if the player owns the hats in Team Fortress 2) be used in Portal 2's co-op modes.

DLC and expansion packs

Name	Notes
Peer Review	Free, included in latest update. Requires completion of the original co-op missions.^[3]
Roll cage	Pre-order only
Paint job	Pre-order only
Antenna topper	Pre-order only
Sixense MotionPack	Included in the limited edition of the Razer Hydra motion controller. (Which is now discontinued.) The DLC is incompatible with the latest builds of the game, and requires the Sixense MotionPack DLC Preservation Mod to make it work on the latest game builds.

Flickering white grainy graphical artifacts on some surfaces

In seemingly rare cases on some specific surfaces, textures can show flickering white grainy graphical artifacts.^[12]^[13]^[14]^[15]^[16]

Use `-vulkan` command line argument^[14]^[17]
Suggested that this happens due to an old Nvidia driver bug causing problems with projected textures that are used by the game.^[14]^[16] Seems to happen only on rare occasions, but especially at first room of chapter 2.^[13]

Tested on first few levels of the game and especially the beginning of Chapter 2. Could only reproduce it at the Chapter 2 beginning room. Saw it on the texture where the laser pointed at and also on the black tiles near the walls close to the exit door of the Chapter 2 level. Tested with latest Nvidia GPU drivers and thus while using dedicated GPU.
