it's a not bad game but bosses play out the same, it's like the game doesn't want to go through next level. it wants you spend money , it does this annoying thing where when you are about to win, all your turrets will fire in the same area and then you lose, it will let the swarm through. the Tesla coil needs fixing too, many times it will go through enemies without hit detection.

Expensive but addicting. Everything in game is super expensive compared to a lot of other gacha mech games. The game itself is addictive, and I do see myself playing it long term. Definitely not purchasing anything as the purchases are mainly to speed up the game so it makes everything easier. In this game either you're a whale or you're F2P. There's no room for you to dolphin, just not worth it.

this game is crooked, I had lost battles when I'm 3 times more powerful than them, and is only because I get so much more enemies at the same time than them. for example I have 500 of power, 5000 of hp, and 80 cards with different abilities, and I loose with someone that has half of it. I spend $50 one time and I could only pass one level with that amount of money. never playing this game again and I'm going to use my YouTube channel to talk about you. my channel is about games. now is your turn
