The survival strategy/tower defense title will be in early access “at least through the first months of 2025,” per Digital Sun.

Digital Sun’s Cataclismo is now available for PC via Steam Early Access after facing a short delay. The Moonlighter developer’s latest title is a survival real-time strategy set in a post-apocalyptic world, where players construct defenses during the day and battle hordes of Horrors at night.

Utilizing a LEGO-like system for building, you can set up traps and choke points while moving units around. However, destroyed walls can damage troops, so monitoring defenses is important for survival. As players gain Prosperity, additional troops, upgrades, and buildings become available.

The early access version includes Campaign Mode with 11 levels across two biomes and full voice-acting, Skirmish Mode and Endless Mode. A Level Editor is also included alongside Steam Workshop support to enable sharing and downloading user-created maps and blueprints.

Additional biomes, levels and more will arrive over time, with the developer expecting to remain in early access “at least through the first months of 2025.”
