not to mention the system of making custom maps into multiplayer maps. This could take a long time. It's a whole different story if the creator decides to make a second AM, instead of adding a multiplayer function to the current one. Plus the whole thing qith server lag and glitches, the creator and the testers can't find all of the glitches, it will take a lot of updates just to make multiplayer playable. and the whole other thing with money and sponsors. The creator may have the ability to make a multiplayer game/version, but he will need the money to do it. There isn't a that great chance that the creator will be able to pull it off. But on the other hand, he may already be working on it. who knows? all we cando now is hope he will be working on it and be able to finish it and make it good.
I'm just being realistic here, but I don't really think that will happen because what will happen when you use adrenalin? Unless he takes out adrenalin or makes it work somehow, I don't think it will happen.
