Shadow of the Tomb Raider is unique in that it'll be the only game in the rebooted trilogy to feature a co-op component. Part of the upcoming The Forge DLC, co-op will allow you to complete challenges with another player, either for fun or speed-runs, if that takes your fancy. If you'd like sneak peek, developer Eidos Montreal has released a behind-the-scenes video of the feature.
The clip, which runs for less than five minutes, goes through the creative process of introducing co-op to the game, and some of the challenges Eidos Montreal faced in making it work. As Gameplay Director Vincent Monnier explains:
The real challenge was actually to build an environment, that you can visit on your own and with someone ... when it comes to multiplayer or co-op, you need to take into consideration the other player.
It gets things more complicated, so you need to account for that in terms of the level art, level design, the VFX, the sound, so the other player always know what is going on.
Monnier goes on to mention that Tomb Raider has always been a "personal and emotional journey" and that the developers "were very intimidated" by the concept. The key to making it work was by asking themselves the important questions, such as "How can we improve the experience?" and "How can it be beneficial for players to be together?"
A total of seven DLCs are planned, with The Forge being the first. It can be purchased by itself for $US4.99 ($6.90), or via the $US29.99 ($41.48) Season Pass.
It's unclear whether future content packs will beef up the co-op aspects, but I'm leaning towards yes, considering how much work went into developing it in the first place.
