We have just released an android demo of our indie premium game Type II https://play.google.com/store/apps/details?id=com.scorchgamestudio.type2demo It's a 3D Hardcore FPS with Tower Defense elements. There are many enemy waves, multiple guns and turrets, large scale maps, giant bosses... oh, and it's set in space. There are no ads and no IAPs, it's a 100% premium game. Someone said that it's like old school PC game but made for mobile - we like that description a lot. It's really well optimized, it can run in 60+ FPS (120 even). Oh, and we have recently added a controller support in our latest patch for those hardcore mobile gamers out there Full game on Google Play: https://play.google.com/store/apps/details?id=com.scorchgamestudio.type2 Website: http://scorchgamestudio.com/type-ii/ Twitter: https://twitter.com/Type_II_TheGame Facebook: https://www.facebook.com/Type2TheGame/
