It's actually pretty fun and kind of unique for a turret shooter game 🤔 Only unique in the fact that you are on a walking mech though. Unfortunately the ads that make you go to the play store will restart the game and you will lose whatever you were watching the ad for. The power of the turret and the health of the enemies are very unbalanced, I can beat most waves with just a regular leveled up cannon and the rest of the guns don't even have a chance to shoot.

This would be a 5-star rating, I really like this game. However, more often than zero times after I watch an ad, it boots me back to the main loading screen. I'm been in the middle of a battle. It seems as though the ads are taking too long. The game can't be "pause offscreen" for too long? My guess. 👍 game!

This game is a great spin on the Tower Defense games. Instead of a castle having archers, mages, knights, defending it's walls. You have a giant mech, where you add different turrets, with different skills. Then you upgrade the different weapons etc. Different types of turrets work better against different crafts sent in to destroy you. I downloaded this game playing it 9hours straight. I love tower defence games, and play store has a lot to choose but this one is one of the better ones, try it
