Compare Human Extinction Simulator prices across trusted key stores and find the best deal. Developed by Machine 22. Published by Machine 22. Released on 1/21/2015. Available on PC. Genres: Indie, Simulation, Strategy.

A 2015 indie tactical space-combat sim that asks you to build a war strategy against alien invasion, if you can figure out what's actually happening.

I went in expecting a grand-strategy setup, but Human Extinction Simulator is really turn-based tactical battles with light strategic wrapping. You're defending Earth against alien fleets, building war plans between engagements. The core loop is solid enough: positioning units, managing resources, executing battle orders. The problem is the UI doesn't explain itself well. Tooltips are sparse, tutorial is minimal, and the strategic layer feels disconnected from the actual combat. If you're the type who enjoys figuring out opaque systems and doesn't mind trial-and-error learning, there's a lean tactical game buried here. But this isn't a Paradox grand-strategy experience, it's closer to a barebones XCOM predecessor. Worth a shot if turn-based space combat appeals to you and you have patience for clunky presentation.

GamerScout Verdict

Rough-around-the-edges tactical space game for players who tolerate obtuse UI in exchange for turn-based combat depth.

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.
