About Waterloo Terminus
In the gas corridors/tunnels, downstairs: make sure the gas is a true killer, leaving no room for revive. Otherwise, you will end up with a situation where two medics run down, revive-progress forward, and manage to pass the gas, without having to repair the pumps first. (Unless that is intentional.) I have not tested this, but i wouldn’t surpirse me if a set of quick medics could pull this off. Just warning.
About that green sofe/trickjump, near attackers first spawn (The sofa is upstairs): It is to hard to do that sofa jump. At least for me.
Also, and I must apology for being such a critic, the CCTV cameras near final objective, they are a bit too big. I know, it is a minor thing, but i am just telling you my absolute initial, first reaction when I saw them: I felt that they were perhaps just a little too big (i.e. change model scale to 0.9 or something like that).
EDIT: adding stuff.
