While messing around with the map I was able to find two intresting gimmicks.
The first being that you could use the box at the edge of bomb site A to jump to the top of the electric box, break the vent, and then hide in that little spot waiting for enemies.
The second one being that near the T spawn a T can hide behind the portapotty and shoot CTs with out them noticing where the T was hiding.
I don't know if the first one is a problem but the sencond one may be a more important issue to adress.
