There's no server browser at all within the TF games for fans to make custom servers for, and that has been problematic these past few months which is why we haven't seen anyone make some custom server for people to play again.
I think the least Hasbro could do now is just hire a reverse engineer company like Bluepoint games and re-code the game to connect to entirely different servers since it's their games still. But hey, alot of source codes for really old games this year have been leaked so it might not be entirely out of the thought. Probably requiring a month or two of full knowledge of how the engine entirely works. A source code would be nice yeah, some games definitely benefited better from having a source code released to the public, but this is still an decade old engine version of Unreal that doesn't receive any support anymore. Even if Activision doesn't own the TF license anymore, it's still Hasbro's property of Transformers. Click to expand.I'd imagine someone would get into big trouble for that though. The Transformers may be more than meets the eye, but Transformers: Fall of Cybertron has an obvious goal: to let you control numerous Autobots and Decepticons while filling the screen with as much.
