At first glance, you may thought this is just another 3d slop game. But its actually a very good designed game. The game lets you upgrades towers, research units and the levels are harder everytime, making the game challenging. The Conquer mode is crucial because it makes the game less boring by having various gamemodes. Overall, great game. I'd like to add some suggestions like online mode where one of the players are the enemy which can spawn enemy units and the other will be the defender.

It has a real smooth feeling to it. no lag or lag spikes. the bullets from the turrets are real smooth when being shot. they also look relatively realistic which is a plus. the ads in the game are nice and spaced out letting you play a couple of matches before giving you a ad. only reason I'm putting it at a 3 star is cause the battlefield looks bland it's just gray and nothing there. only color is the enemies, the turrets, and your base, and some enemies spawn outside of the screen of gameplay.

the game is alright but the way they shove ads down your throat is crazy. everytime you get a reward or get gems, they ask if you want to watch an ad to double it. after 2 rounds or sometimes even after only 1 round they force you to watch one of those stupid short double ads. when you upgrade your main weapon, it only improves the damage, it doesnt improve the aim at all.
