A really cool and fun game with decent graphics and enemy designs. The biggest issue is the difficulty curve. I'm up to normal stage 35 now and, without spending money, it takes around 3 days to grind enough coins/components to upgrade turrets to a decent level. The RNG element when selecting turrets can be annoying as well. Also, Ā£50 for no ads? Absolutely insane!

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.

The more cards and turrets you have, the less chance you will get the one you want. The game forced you to have more of the choices to choose but in fact you know what really need to use for playing each state. Why forcing players to choose the cards/turrets that they do no want. To make the game playable is to let players choose what they really want to use. This helps players to think strategically and encourage positive impact on human development than relying on just lucks.
