It is a game that pays to win, you can level up if you are patient, but the items that you need to enhance in the store are limited, so you have to wait for the store to refresh, you will only get the new mechs by spending lots of cash or time, Even watching ads, you will only get so far, for instance Mech Vault needs you to pass level 20, doing all the quests and watching videos you will be lucky if you get to level 8, without spending, and it's a similar story with other events.

I changed my review to 1 stars. The game is fun, and I enjoy it. however, the mech vault events are very much a money grab, and as you get further in the event/level, you notice that your luck goes bad very quickly. this is the second event I have played and paid into and there is no way it should take nearly as long to progress through the event when you have a 1 and 3 chance to pass a level but takes consistently 8- 15 times. FIX THIS it is not right to scam your players

I think this game is awesome, but it's pay to progress and P2W. It's impossible to play if you don't spend thousands on this game. DON'T BUY PASSES, WON'T HELP YOU PROGRESS. Battle passes, £9.99 or £29.99 to get full rewards. Monthly passes £4.99 and £19.99 To get red mechs locked behind recharge for rewards, spend £1999 within a limited time before it resets. Special mechs locked behind spins, 100 spins £99.99 with 0.5% chance. There is still a lot more that requires money. Game for the whales.
