[ Chat block from saying im the killer]
Plot hole, the murderer disconnects. Then it's only a matter of time for everyone to figure out who can't talk.
I would also like to add an idea.While everyone is exploring the house the killer should at least be able to pick them off one by one. Whoever the killer kills it will not show their name on screen but it will show the death of the name they killed. They should also be limited to being able to kill by at least a two minute delay.Also remove the dead from being able to talk.
You'd need competent players.It would turn into an EVERYONE HIDES IN ROOMS WITH WEAPONS.
If you have Garrysmod, you should look at Trouble in Terrorist Town. It's exactly like you said, except instead of one killer, it's a group. When people die they can't talk, and there is no kill info ( Player1 < Player2).
Also i already stated players cant run around and randomly attack..They have to be hit by the killer.
What if you clearly see the killer infront of you and hes shooting/chopping at you and he misses, and you cant defend yourself?
