How to play COOP [SourceCoop Mod]

Community servers can be found in:

• Server browser - look for coop or maps beginning with "bm_"
  
• Our Discord[discord.gg]

If you want to play just with your friends, you have to host a private server.
Please understand, that in order to make your server accessible over the net, you have to either:

• Port forward 27015-27030 UDP (Current status can be validated by pasting your public server address in https://ismygameserver.online/)
  
• Run a network tunneling service on the host, e.g. playit.gg
  
• Connect the host and all players by creating a virtual network, e.g. Radmin or Hamachi
  
• Beg the developers to add Steam networking to the game (Steam Datagram Relay)

If you do not do this, your server will probably be limited to LAN (Local network).

QHow to save progress?

AYou have to manually choose the map (see below), but you can save & load player state with sc_save and sc_load.

QHow to change maps?

AUse sm_map mapname or changelevel mapname commands. Check this guide for complete map list.
Alternatively, all players can start a map vote by typing /changemap in chat or using the ingame SourceCoop menu.

QHow to set the difficulty?

ABy default, difficulty is set to increase by 2 per player. To set it manually, use the command sourcecoop_difficulty_auto -1 and sourcecoop_difficulty x where x is a number from 0 to infinity.

QI'm getting 'your map differs' error when connecting to a server.

AIt can mean 2 things, either you're in different branch of the game than the server or have a mod installed that replaces stock maps (like OAR Uncut).

QI'm getting 'unexpected authentication protocol 1675212' error when connecting to a server.

ADid you install SourceMod into your game client? If so, disable/remove it.

QI found a bug.

ACheck if it's already listed under issues on the github, otherwise add a new issue.

QI want to help.

QIs this compatible with Blue Shift?
