There are two bad spawn-camp areas, one on each of the new maps, right at the first spawn. An experienced Defense team can easily spawn-camp the Attackers, as described below:
Founders’ Tower: If the Res team can defeat the Sec’s initial push into the Lobby Door Control area, they can then work their way towards the Sec spawn area. This is an area that is very easy to camp. I’ve been able to get all the way down to the Spawn side exit area at the bottom right, and get myself into the Butterfly Corner so the auto-turret can’t see me. From that location, I can easily snipe and lob grenades into their spawn.
Here is that area (screenshot from the Brink wiki):
Labs: If the Sec team can defeat the Res’ initial push into the Elevator room, the Sec can setup a few players on each curved ramp outside, go all the way down near the bottom of the ramps and look right into the Res spawn. The auto-turrets don’t even fire at you even if you’re looking right at them. If you shoot at the auto-turrets, you get the warning that “YOU’RE IN THEIR SPAWN AREA!” but the auto-turrets don’t fire back.
Here is that area (screenshot from the Brink wiki):
My suggested solutions:
Founders’ Tower: Move the bottom right Auto-Turret to the left so it can see someone in Butterfly Corner and perhaps add some glass walls/barriers up the larger ramp in that area that the Attackers can hide behind as they work their way up.
Labs: Put the Auto Turrets closer to the bottom of each ramp and give them a longer view range so the D can’t just park themselves in plain sight of the Attackers’ spawn and snipe.
