If there’s one thing better than looting the artefacts of ancient, forgotten civilisations for personal gain, it’s doing it with a friend. Today, the first of seven planned DLC tombs for Shadow Of The Tomb Raider was released. The Forge is a lava-filled, puzzle-heavy delve, and designed for play either solo or in the newly introduced online co-op mode. Lara can now tag along with a pal and solve problems in fun tag-team ways, further building on the back-to-basics tomb raiding approach of the game. Below, Eidos Montreal show off some of the quirks of multiplayer.
