So here are the steps:
1: Immediately go to electrical after game starts
2: Pretend that you have both Download and Wires, this gives you more time to wait in electrical. If no one enters during this time, walk away and act like nothing happened.
3: If someone walks in, kill them, then vent to medbay. Try and kill them an area so that it isn’t viewable where lights are off and everyone is standing at lights, but immediately becomes viewable once they are turned back on.
4: stand by test sample test and sabotage lights
5: head to electrical, but take the long way (via caf) no one will see body as lights are off.
6: once lights are turned back on, everyone will assume that whoever was the first person at lights was imposter. Try and be the person to shoot WHO WAS FIRST AT LIGHTS as it makes you less sus.
I have used this multiple times and every time has led to an imposter win. 😊
