What a fantastic game in so many ways! Unfortunately, it suffers from giving no sense of progress at all. From the first level on, you can only raise to level 20 each run, meaning 19 cards spread around your five turrets. Because of that, you have as much chance of upgrading your turrets to an awesome level on day 1 as you will have on day 30. The limit never raises, so you leave every single battle feeling frustrated at being unable to upgrade everything you want. In the end, unsatisfying 🙁

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, £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.
