  • Fixed bug caused by code being in debug mode (don't ask how that happened, I couldn't tell you)


  • Made the code a little more friendly for other mods to interface with
  • Devs looking to block certain items from dropping should check out the DropInMultiplayer.AddInvalidItems(...) method (and/or send me a message)
  • Devs looking to temporily block the join_as command should check out the DropInMultiplayer.BlockJoinAs(...) method (and/or send me a message)


  • Filtered out illegal items from possible drops on joining game, big thanks to paddywaan ( for submitting the pull request


  • Added support for custom characters which have spaces in their names (just type the name without a space, e.g. join_as ClayTemplar)


  • Fixed bug which broke Captain's R ability and PlayerBots mod


  • Added ability for other mods to temporarily block join_as if needed, shoot me a message if you need help setting that up
  • Added temporary block for join_as on the final stage to prevent soft lock


  • Fixed issue forcing all players to have the mod installed, you should now be able to have players without the mod use the join_as command in chat
  • Removed a debug log I left in, whoops


  • Fixed issue preventing some modded characters from being selected (specifically BanditClassic)


  • Fix for join_as from captain to any other class keeping his unique item
  • Fix for boss items preventing joining
  • Fix (hopefully) for join_as working while dead if you are controlling a drone (FallenFriends)


  • Fix for interaction with FallenFriends, not longer breaks join_as if you have FallenFriends installed


  • Added option for join_as after character select (letting players change characters). Defaults to false


  • Release a probably broken build
