I run a TF2 server, and I want to customise the in-game vote menu, without using sourcemod. The reason is, I want to add extra MVM maps (not official ones) and I want the players to be able to select which map they want to play by the vote features.
So, I found the way to do this:
First of all, in your server.cfg, set the
tf_mvm_missioncyclefile parameter. The default file this points to gets overwritten on server updates.
Then, copy the file
tf_mvm_missioncycle.res to your chosen file set in the parameter above.
Finally, edit this file to taste (I won't provide example here, its fairly straightforward).
