	As you can see here, the water under the bridge has been completely removed, so that anyone swimming in the water would be completely visible, even without GL water enabled.
	Here you can see that the walls on the edges of the sniper deck have been removed. This allows the cheater to see enemy snipers from behind the walls without being at risk, and also to see enemy snipers who are hiding behind the walls themselves.
	This shot shows how easy it is to see into the ramp room from the grate area, allowing the cheater to work out where the defenders are before he enters. The same applies looking outwards from the ramp room, a cheating defender would easily be able to see anyone incoming from the grate or using the side passage due to the fullbright and invisible walls.
	In this picture we can see the view from the top of the lift shaft, looking downwards. As you will notice, it is very easy for the cheater to see whether there are any nasty surprises waiting for him at the bottom of the lift.
	Here at the upper respawn, the cheater is able to see people using and exiting the respawn room.
	This shot shows the spiral ramps leading down to the basement. As you can see, it is very simple for the cheater to see one spiral ahead, which makes surprise attacks very difficult for his enemies. This also makes spiral sentry guns very easy to destroy.
	In this image we can see the flag room, or what is left of it. Obviously the removal of all the walls (pretty much all over the entire basement, in fact) gives an enormous advantage here. Any sentry guns located in the flagroom are easily seen and dispatched with.
