I know this already has a old feedback post, but I want to give my own input. The neighbor needs to have more ways to split up explorers and/or slow them down in gameplay. The gates can help but the problem is the neighbor has to be nearby them to work it most of the time which is why I'll suggest a few things:
Give ALL neighbors the remote control for gates and keycard doors, so as long as your neighbor form you can open or close them and help set up ambushes or stop a explorer from escaping. It's important when I say this that you do NOT give all neighbors the ability to detect explorers on the remote control as that'd ruin stealth. Maybe to encourage still using the clocks the remote control would have a slight cooldown between every use to prevent spamming too.
For my next point, please add more gates around some of the maps. Map 2, 4, and 5 only have one gate that's actually in the way of gameplay and in all those cases they can easily be gone around. Maybe if quite a bit of gates get added they can be randomized every round, like some matches gates would be spawned in some places and others they'd be gone.
Maybe also add some other traps, like weak floors that break if too many items and/or players are on them.
