The game does need more work, but the developers are getting there. Love the option to rush upgrades by watching a few adds in app that only take 15-30 sec. I wish Clash of clans would do that!!! I do wanna say that some of the troops need a little more dmg and health, also the drones that destroy walls need a better ai, its cool that you can see their path before you deploy them but moving on a straight line doesnt always do the trick!!! For now thats all i can think of thats holding me from giving this good sci-fi game 5 stars!!! Please keep it up guys!!! Dont wanna see another sci-fi game been shut down like they did with "Dark district"
