Currently in development and quite early on, The Farlanders is a tile-based city-builder set on the red planet Mars. Created by developer Angry Kid, the same behind Undervault a free roguelike dungeon crawler.
Even though it's not finished, it's starting to really look good and it's already engrossing enough for me to recommend taking a look at it if you're in the mood for a city-builder that's a little different to the rest. It just recently had a big update, which you can listen to the developer talking about below:
You have to balance food, water and power with limited expansion possibilities early on. As the game progresses, you gradually expand by terraforming small parts of the map. They already have another update in progress, which should hopefully be released next month.
You can try The Farlanders free in your browser on itch.io and buy the standalone version to support further development on for $5.
