Castillon

Castillon Has Grown—a Lot!

One Up Plus

We’ve been having an absolute blast working on Castillon, and we’re so excited to share how much has changed! The game is feeling bigger, friendlier and much more satisfying to play, with new ways to customise your wizard, build your defences and survive each night.

There’s plenty here whether you enjoy planning the perfect base, unlocking new toys or watching a huge wave run straight into your carefully prepared defences. Here are ten highlights we can’t wait for you to try:

  • Continue your adventure from the beginning of your latest day, instead of starting the whole level again.
  • Dress up your wizard, choose equipment and spend stat points in a completely refreshed Loadout and Stats screen.
  • Complete level challenges to unlock new weapons, outfits and difficulty options.
  • Summon a loyal spider friend or surround yourself with the new enemy-melting Decay Cloud spell.
  • Enjoy a smoother Draft experience with clearer rewards, reliable rerolls and a friendly introduction for first-time players.
  • Build better walls with snapping, easier rotation and much less fiddly placement.
  • Select groups by dragging with the mouse, then send your troops out together with more dependable commands.
  • Face enemies that navigate the battlefield more smoothly—even when the screen fills with a massive wave.
  • Meet a growing family of fiery new monsters, including the Lava Naga, Lava Rock and Lava Salamander.
  • Explore refreshed menus with prettier styling, friendlier controls, clearer controller navigation and more translated text.
