Mars terraforming sim that adds water mechanics, but the foundation game's mixed reception suggests you should know what you're signing up for.

Per Aspera: Blue Mars is the aquatic expansion to the base terraforming strategy game, introducing oceans and water-dependent systems to your planetary engineering workflow. If you've already sunk time into the core game and want fresh resource chains to optimize, the water cycle mechanics offer real logistical depth. The addition of coastlines and hydrological infrastructure creates new spatial planning puzzles that aren't trivial to solve. The catch: the base game sits at 44% positive reviews, which means this DLC is anchored to a foundation that already frustrated half its players. Before buying Blue Mars, confirm whether the core game's pacing, UI density, and simulation complexity work for you. This expansion doesn't fix underlying systems, it extends them. If you bounced off vanilla Per Aspera, more water won't save the experience. If you're a systems-oriented player who thrives on interconnected supply chains, it's worth testing the base game first at a discount. Diego, Scout Team

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.
