If you are running unarmed from a murderer, you cannot sprint and they can, so running down a straight hallway is a bad decision. Crouch-Jumping is a good method to get away. On the CS_office map, for example, you can jump over the computer counters in the main big room with the floor-to-ceiling windows and cubicle sections with the counters. You can crouch-jump through them and the murderer has to take a second to stop sprinting and crouch jump through it. Usually the murderer does not expect you to slip away so easily, and the confusion could keep them back too. If you keep crouch jumping over things, he will be at your heels if he is good, or give up if he is bad or doesn't know how to crouch-jump himself. The murderer CAN throw his knife to get you, but if you do it right he wont be able to get a good throw at you. Be quick (obviously), crouch jump over as many things as possible, and keep the murderer in your sights at all times if possible to know where to jump next.
We don't have sprinting on the TTT server Porcupine. He's talking about the seperate gamemode, Murder.
What would the rules be for a murder server.. Only things i can think of would be disrespect and hiding in cheap spots
