ok let me explain how my map works for assault mode:
1.The red spawn Never moves for it is a base and is in the middle of all checkpoints.
2.The Blue spawn will move to the correct base.
3.The game is played by blues defending in bunkers/catwalks at the base and trying to shoot the reds down
4.The checkpoints are holes in the ground that you jump into that will teleport you back to the top
5.When a checkpoint is hit a gate will open up back in base a wall will come down leading to a warp pipe (for reds) and lead them back to base but for blues the floor moves and they land on a teleporter which takes them to the second base.
