make it with more detale, bigger maps, more realilistic aliens, and two sepret modes an arcade mode and a adventure mode where their are like 40 levels that you have to beat. And arcade mode is endless getting harder and harder as you go in and when you die you can put in on the leader bords, that's all i think it needs. I hope you use the idiea and good luck with the game bro.:)
