I will refer to team killers as TKers from this point onward. There are different types of TKers who play the game. The table below shows who they are and what they do.
The next section will tell you how to deal with TKers in general.

There are a few ways to deal with them.

The obvious and most common method of dealing with TKers. If you see someone purposely shooting you and/or your teammates, call a vote to kick them out of your game. Let your teammates know that you are kicking the TKer. Unfortunately, this method won't work if the TKer brings a partner with them. All you can do is leave the game or, if you're lucky, let the AI director screw them over. If you do leave the game, don't forget to report and block them.

WARNING: This method will do more harm than good since you will be dealing a lot of team damage. However, if you just want to defend yourself or if you want to make those TKers suffer the consequences of messing with you and your team, this method is for you.

Basically, you see someone killing a teammate, you SHOOT THEM BACK before they get the chance to hurt you or another teammate. If they attack you first, let your teammates know ASAP (if you're not downed by them, try to move away from their line of fire and retaliate). If you manage to down them first, don't hesitate to call a vote to kick them after that. Before kicking you may say "YOU PICKED THE WRONG HOUSE, FOOL!" to the TKer if you wish. Heck, you might be satisfied after making those idiotic TKers get a taste of their own medicine.

Use the power of an admin to teach those TKers a lesson. Go to Steam Workshop or Gamemaps and download Rayman1103's Admin System. Once downloaded, host a Local Server with the addon enabled. Doing so will give you admin control and thus access to admin commands. Play the game normally, and if you see a TKer in your game, you can type the following in the chat (without the quotation marks):

• "!incap nick" or "!kill nick" if the TKer is playing as Nick
  
• "!incap louis" or "!kill louis" if the TKer is playing as Louis

If you are new to the game, I strongly suggest that you learn the names of the survivors so that you know what you are doing. I repeat, YOU NEED TO HOST YOUR OWN LOCAL SERVER FOR THIS METHOD TO WORK.

There isn't much to mention in this guide and I'm sure most of you know how to deal with TKers even if I didn't post this. If you don't, now you know after reading it. Happy fragging.
