The following commands do not require you to enable cheats and can thus be used in public games and ranked.

• mm_prefer_solo_only — If you prefer playing with other solo queue players
  
• citadel_unit_status_use_new true — new health bar

[OUTDATED] but you might still get something out of it / figure our how to get it to work, I'm currently quite busy :(
[DISCLAMER] This section has been shamlessly stolen from https://deadlocked.wiki/Console_commands

• The host starts a custom game by loading into the map with map street_test
  
• You may want to pause the game immediately after joining by pressing P to give other players time to join the match.
  
• The host finds their ID by running status
  
• Find a green line in the console that looks like this: [Client] steamid : [A:1:XXXXXXXXXX:XXXXX] (XXXXXXXXXXXXXXXXX) (the Xs will be replace with numbers)
  
• Select the part after steamid that looks like this, including the square brackets: [A:1:XXXXXXXXXX:XXXXX]
  
• Right click and choose "Copy Selected Text"
  
• The host sends players the ID they just copied. Players can now connect to the game by opening their console and running connect [A:1:XXXXXXXXXX:XXXXX] (replace the part after connect with the ID they got from the host).
  
• Upon joining, players will be able to select their team and hero. To bring up this menu again, players can run changeteam 0.
  
• If you ever want to restart the game, the host can run changelevel street_test.

• On the main menu, before you start the game, run exec citadel_botmatch_practice_6v6_hard to load the bot config.
  
• You can replace hard with easy or medium to choose the bot difficulty.
  
• If you're already in a game, you can perform these steps then run changelevel street_test to restart the game instead of starting a new one.
  
• Run citadel_spawn_practice_bots false so that bots won't spawn immediately when the game starts.
  
• Run citadel_spawn_practice_bots_count 12 to ensure that bots fill all remaining slots (they'll be added until both teams have 6 players).
  
• Start the game (i.e. map street_test) and press P to pause the game during the pregame (as soon as you load in).
  
• You can use citadel_pregame_duration before starting the game to increase the duration of the pregame if you want.
  
• Allow all other human players to connect and select their team and hero.
  
• The team/hero menu can be a bit glitchy. Players can use the changeteam command instead (see table above for command description).
  
• Remember to choose your (the host's) own team and hero as well. This may automatically unpause the game - press P after selecting a team to pause again.
  
• After all human players have joined teams and selected heroes, the host runs citadel_spawn_practice_bots true, then presses P again to unpause the game. Bots should fill the remaining slots on each team.
