Co-op Is Now Available in the Castillon Demo!

One Up Plus

Hey everyone!

You can now defend your castle with a friend! Two-player online co-op is available in the demo, so you can build, explore and fight through The Glade and Templar’s Rest together.

Play together

  • Invite a friend through Steam, choose your loadouts and get ready in the lobby.
  • After a run, you’ll return to the lobby together to prepare for the next one.
  • Fixed clients being unable to collect certain chest rewards.
  • Fixed gamepad input reaching the Main Menu while the multiplayer lobby was still open.

Fixes and improvements

  • Added a Medium graphics preset and a VSync option.
  • Reduced unnecessary GPU use on the Main Menu.
  • Tidied the Wizard Loadout screen and improved controller navigation in Settings and confirmation menus.
  • The Quarterstaff now fires its own fireball, with new impact effects for fireballs, spears and bone bolts.
  • Improved enemy pathfinding around destroyed buildings and blocked routes.
  • Fixed challenge bars appearing before the Defeat screen had faded in.

Full game updates

  • Added the Lightning Rod, Gold and Purple Capes, and Obsidian Hat as challenge rewards.
  • Adjusted Ember Hollow’s enemies and three-star requirements, and fixed enemies getting stuck in the gorge.
  • Improved enemy attack warnings with distinct effects for the fire, undead and forge enemies.

Thanks for all the feedback and playtest reports. Give co-op a try and let us know how you get on!
