3dGecko Studio

The game studio behind Holdover, Janolith, Gateshock and Hearthpiece

We're building Holdover, non-violent long-range precision shooting, Janolith, a word roguelite with two-sided stones, Gateshock, a tower defense with a playable demo, and Hearthpiece, a cozy jigsaw puzzle that's free on Steam.

New from the studio

Holdover – Long Range Sniper Simulator

One shot. A thousand metres. And the wind decides.
