Compare Planetoid prices across trusted key stores and find the best deal. Developed by GameWriterStudio. Published by Conglomerate 5. Released on 2/24/2017. Available on PC. Genres: Action, Adventure, Indie, Strategy.

A 2017 physics builder where you construct defensive facilities to protect humanoids from waves of enemies. Niche and rough around the edges, but strategy-minded players might find something worth tinkering with.

Planetoid is a physics-based building game that asks you to construct facilities on a small planetoid to defend your humanoid population from incoming threats. You're managing both placement strategy and real-time combat outcomes, which means poor building decisions cascade quickly once enemies arrive. The trading-card layer suggests a progression system, though documentation is sparse. I'll be direct: this is a 2017 indie title with no Steam reviews and zero Metacritic coverage, which tells you something about its reach. The concept of physics-based tower defense has legs, but execution matters hugely. Without player feedback or modern updates, it's a gamble. Worth a look only if you're specifically hunting obscure building-strategy hybrids and have a high tolerance for rough UI and limited documentation. Diego, Scout Team

GamerScout Verdict

Niche physics builder with real-time strategy bones, best approached as experimental rather than polished.

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.
