Coming November 11th!
One Up Plus
Castillon's development has been on and off for nearly 2 years now. But the last ~6 months have been full-force on making this game the best it can be!
CASTILLON will launch on NOVEMBER 11TH
The game will be just $9.99, with a special launch discount
You can play the public demo NOW as a part of the Steam Next Fest. And we recently added the ability for 2 player LAN/Online co-op. So hit up a friend and test your might in the first 2 levels ( The Glade and Templar's Rest ).
The core gameplay has been tightened up a great deal since the initial demo released, working to find our intended balance between strategic TD, and accessible mini-RTS. And more recently, we've had the fun process of enhancing as many visuals and effects as possible. The battlefield should feel much more lively with all this in place!
We are eager for more feedback, both in singleplayer and co-op. Please consider dropping a review on the demo page. Or join the One Up Plus Discord to chat with the devs directly.
And be sure to add Castillon to your Wishlist!
