a simple change but it would be pretty cool

instead of being stopped when you touch the edge of the map you go through to the other side

only up and down so you can't cheat to the intel

You could cheat to the intel still by when going up on the map the intel is down there on the map so u go up and end down and bam INTEL-GET and then u would just have to get to the base.

damn straight, also people could move through it to avoid getting killed

I think it should be an option, but definitely not default.
