- Catamyst v1.2: Wave Modifiers, Menu Overhaul & More! - 2 February 2026
Hi! Catamyst v1.2 is finally here! It took a bit longer than expected as... I kept adding stuff to the update. Whoops. Anyway we're finally here and the update is out now!To start, Catamyst has a new logo! Your library should update all its assets soon with the brand new design, and you'll see it in the Main Menu in-game. Next up, are Wave Modifiers - unique effects that have a chance to occur every single wave. These modifiers replace the former "Negative Modifiers" that you'd find attached to rare Enchantments. Unlike the previous modifiers, these aren't purely negative. Instead, they'll find ways to change up how you manage the wave.For example... Heavy Rainstorm!This wave modifier slows all enemies down by 10%, I guess the Barcs got waterlogged or something.You'll notice some darker lighting and even the rain splashing off of Willow's head (the rain can even hit your cursor!).As a s…

- Upcoming Update: Catamyst 1.1 - 1 September 2025
Just popping in to quickly tell you about the next Catamyst update...v1.1: Part OneI wanted to let y'all know what's going on with the 1.1 update. Since announcing the update, I've started full time work and so my time to work on the game has been limited. Rather than just let the updates that ARE done go to waste, I thought it'd be better to finish up what I'm doing and then push it out as part one. I'm still working on some finishing bits, and then testing, but it should be ready to go relatively soon. I won't promise a release date as I don't want to overpromise.What's in Part One?Here's a brief overview of what's included in the next game update:ReworksStatus Effect system overhaul, including stackable buffs, potion-specific effects and more.New Ward shielding system (+ upgrades), replacing Overheal and Damage Reduction."Imbued" upgrade overhaul (new and better effects!).Catalysts n…
