Compare Sanctum prices across trusted key stores and find the best deal. Developed by Coffee Stain Studios. Published by Coffee Stain Publishing. Released on 5/15/2013. Available on PC. Genres: Action, Indie, Strategy. Metacritic score: 77/100.

Tower Defense meets first-person shooter, where you build mazes and shoot aliens simultaneously. Niche, but genuinely inventive if you're willing to learn its systems.

Sanctum is a 2013 hybrid that nailed a concept most studios wouldn't touch: real-time tower defense played from an FPS camera. You build defensive structures to funnel enemy waves, then pick up a gun and defend the objective yourself. The core loop works. Four character classes offer distinct playstyles (damage, support, crowd control, mobility), and the build-order decisions matter. Upgrading paths between rounds reward planning, not just reflexes. The weak spot is obvious: it's stuck in 2013 tech, and the solo campaign paces awkwardly. Multiplayer co-op is where the real depth opens up. If you find the audience, the interplay between tower placement and live combat is genuinely tactical. It's not for everyone, but strategy-minded FPS players who respect building games will find something worth their time. Diego, Scout Team

GamerScout Verdict

For strategy players who want to shoot things instead of watching automation, unique enough to warrant a look if co-op depth appeals to you.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
