Sentinels 1 and 2 were built on a very iOS specific game engine, and porting them across to Android would be a massive time-consuming headache, unfortunately 🙁 A lot of Sentinel players also like Space Station: Frontier, so maybe have a crack at that.
There’s no further Sentinel news right now, but keep your eyes peeled – depending on what you’re looking for we may have something for you soon.
