Nearly two months after release, Square Enix has patched the PC version of Lara Croft and the Guardian of Light to enable two-player co-op online.
You could play offline with a friend on the same machine beforehand - a feat easier accomplished on console.
The PC patch - which also tweaks game controls, performance and visual/audio - is available now on Steam.
Both PS3 and Xbox 360 versions of Lara Croft and the Guardian of Light already have this patch.
The Xbox 360 also has the first batch of DLC, which hasn't yet been dated for the other platforms.
Played from an isometric viewpoint, LCGOL was an experimental spin-off for Crystal Dynamics in a flagging Tomb Raider series. The result was a critical triumph - the game earned an enviable 9/10 here on Eurogamer.
