I dont think living room is fitting for VSH cause of the tight spaces and that the Boss there can get fucked up easily, VSH itself is already a shit show really.
FF2 in the other hand has it easier, I think it's self explainable why it is if you've played the Gamemode longer than for a few days, but a short Explaination anyways: Improved stats overall as in having a gun that deals good damage and increased ammo size, long Ubercharges upon rage, strong passive Knockback reductions.
Otherwise, the Super Market isnt as bad as it sounds, i've played on that map couple of times.
