Information All versions require Steam.

[edit] PlayStation 3

Information PlayStation 3 copies of the game include a Steam code for use on the PC.[3]
Information Each PlayStation 3 copy can only be linked to a Steam account once, so take care if buying the game used - all the benefits from linking to Steam may not be available. Similarly, purchasing one PlayStation 3 copy of the game will not allow co-op play with someone using the included PC version.
Advantage Can be linked to a Steam account, which also gives you access to both the PC versions of the game. In addition, linking to Steam allows cross-platform multiplayer with PC players, access to your Steam friend list (chat, invites, etc.), Steam Achievements, and Steam Cloud save-games (not compatible with PC versions).
