There are a few problems with halo 3’s forge that is kind of game breaking on some maps, if you try to create some sort of infection map like garbage man or Halo on sandbox . So there are a few things 343 must add in to halo 3’s forge and that is, you have to be able the switch teams in game because you cant do that and the other thing is that you have to let us change game mode in game too. Because in halo 3 on the 360 you could change the game mode in game but now you cant. And also the lighting on sandbox is totally broken too. I know this isn’t the most important problems in halo mcc but it shouldn’t be too difficult to add in these changes and fix sandbox so i hope that they can fix it as soon as they can.
