1. what is /mercy for?
2. how do i have to write a the ´´/setteam´´ command? i tried to change myself to team charlie in inf but it didnt work. (yes, i did host the server)
3.is it possible to load multiple bots with the ´´/addbot´´ command instead of 1 by 1? (zombie matches)

1. It's another way to kill yourself.
2. /setteam1 numgun
That would set you to team 1/alpha.
3. Add the first bot using the /addbot command and then use this command: //
That will repeat the last command.

hmm... the setteam command doesnt still work : /
maybe coz i have a spanish keyboard?
and is there anyway to do fake death?

Well, if you prone and aim to the bottom of the screen, mmm....

For the setteam command use /setteam3 1

"/setteamTEAMNUMBER PLAYERNUMBER" 1-alpha 2-bravo 3-charlie 4-delta
For example "/setteam3 1" This would change the number 1 player to charlie.
Fake death? No, but you can prone when bleeding to fool few Major's.
