As part of the season of DLC for Shadow of the Tomb Raider, a co-op mode will be launching on November 13 in The Forge expansion, allowing players to share Lara's most recent adventure. This feature is detailed in a new developer diary video from Eidos Montreal who talk about the opportunities and challenges cooperative play brings to the game.

Eidos Montreal wanted to allow players to work together in more tombs and more modes in this iteration of the recent Tomb Raider reboot series. Building an environment to play by yourself and with someone else can make things very challenging to design, but they liked having the challenge. Co-op utilizes time and space that gives you access to new places. Players can ping things in the game to point out what they would like their partner to do. A speedrun mode requires players to be in-sync in movement in order to achieve top scores.

Co-op play also came to the previous entry in the series, Rise of the Tomb Raider, as DLC too, though this was for its Endurance Mode that challenged players to keep Lara alive in the Siberian wilderness while hunting for an artifact. Each piece of DLC for Shadow of the Tomb Raider includes a new tomb, with The Forge beginning seven months of expansions. A season pass includes every bit of DLC for $29.99 though they can also be purchased separately at release for $4.99. Our review for Shadow of the Tomb Raider found it solid but also lacking the same highs as previous entries.
