The premise, in the publisher's words
Circuit Keep is a grid‑based tower defense game where players build and upgrade circuit‑themed defenses to repel escalating waves of intrusions. The game features a campaign of handcrafted lattices, a research system, and multiple enemy types with unique behaviors. Players manage resources, optimize layouts, and adapt to changing threats across increasingly complex maps.
How it plays
It is played from a bird view / isometric perspective. Its themes are science fiction. It is a single-player game with no multiplayer component.
What you need to run it
The minimum specification calls for Intel Core i3-4000 series / AMD equivalent (2 GHz dual-core), 4 GB RAM and Integrated graphics with WebGL 2.0 support (Intel HD 4000 or better). At 4GB of RAM, it will run on essentially any working PC — that is below what a budget laptop ships with today. Both tiers are compared side by side on the requirements page, and you can check your own parts against them without installing anything.
