In his Surviving Mars review from 2018, Alec Meer said the game managed to squeeze a few happy tears out of him, as he humbly watched his colonies survive, thrive and birth a first non-Earth baby. He added that the game is attractive, has a good soundtrack, and is “adept at keeping superficially complex elements manageable”. “I relish the new state of sustained fear Surviving Mars brings to city sims,” he wrote. “It means that even small accomplishments feel so much bigger.” Head over to Steam to claim Surviving Mars for a very reasonable 100% off. The offer lasts until 6pm BST (10am PT) today, so you have a few hours left to grab it. This freebie coincides with the release of the game’s latest expansion Below & Beyond, which came out yesterday. It adds more tools to help you expand your colony, including stuff that will let you burrow underground into caves and lava tubes. Sounds like a bad idea, but a fun one nonetheless.
