Enigmata: Stellar War is a free tower defense game developed by Roshan Gamage for Android users. As the Unit Commander, you are tasked with building a base and protecting it against swarms of enemies in the galaxy. This game provides extreme customizability and no limits to how you can design your base. With real-time skills, you can fight enemies and battle your base against other players in the SW Battle Arena. The game features over 15 levels, more than 25 units to build, bonus games and missions, and a soundtrack by Hypnoprism. Plus, it is ad-free!

For those who want even more content, there is a one-time purchase that unlocks three extra levels, new units and features, and the ability to battle other bases in the SW Battle Arena. If you have an older phone, you can improve performance and reduce the likelihood of crashing by turning on "Low Res" in the Options/More Options menu.
