Corehold

Corehold is a tower defense roguelite where you hold off thousands of creatures at once.

We lost the surface and went underground. Now the Core rises to take it back. Craft your Weapon from parts, build a new fortress every run, merge to grow stronger, then develop your underground Outpost and take back the surface, one sector at a time.

Coming to Steam Early Access in December 2026. Here you'll find the trailers, development updates and Shorts.

An idle tower defense game with real incremental depth: research that keeps running while you're away, AFK runs, offline progress and Ascension (prestige).

Made by Corehold Games in Godot.
