Hello,
We at Cobalt-57 know the fans of FIREFIGHT RELOADED want something big, and that big thing is multiplayer. However, there was a bit of a hard decision to add it into the game as we didn't know how to implement it in fully. After a while, we finally came to a decision on how we will add in the multiplayer.
The FIREFIGHT RELOADED MULTIPLAYER EXPERIENCE will be its own separate FIREFIGHT RELOADED experience that will focus on co-op gameplay. That's all the details I have about it for now, as it is currently in VERY EARLY DEVELOPMENT and will probably take a few months to finish. However, it will be released with the second part of the STEAM REVOLUTION UPDATE once finished or in a stable state.
If you want to suggest ideas for the FIREFIGHT RELOADED MULTIPLAYER EXPERIENCE, talk about it here: http://steamcommunity.com/app/397680/discussions/2/451850849186707959/
