NOVA was one of the first successful first person shooters on Android. NOVA Legacy is the latest installment and it’s already one of the best free Android games. It comes pack with better than average graphics and controls. There is also a story line, online multiplayer mode, and a rudimentary crafting system. The story is sci-fi based and that means there are plenty of fun things you don’t get with more realistic shooters. It’ll no doubt be one of the best games released in 2017.
