Game is a lot of fun. However Progression is sketchy, Liberation levels are supposed to be 15% success rate, but in reality its closer to 1.5%. hitting max level would cost tens of thousands or years of farming. Just not practical. Game gets new players but as soon as they meet the wall they all quit. Plenty of ability to farm liberation stones in small amounts but overall I just used 600 to go from lvl 3->4 max is 20x all the units. until this is fixed, there will be no real way for Progression

I enjoyed this game until I unlocked liberation for Super soldier. 20% chance to get him to liberation 6. Used 300 universal tokens and 300 Super soldier tokens. Lost ALL of it from a 20% chance to upgrade him. I spent $70 to NOT go up one level! Can't even imagine how much money people are spending to get him liberated... I feel like I'm at a Casino and just lost $70 in one slot machine spin. Horrible horrible horrible leveling system!

I love the game very much. it has so many ways that you could play the game and it's generally enjoyable but since I play it so much it does disturb me that a lot of very essential things like having 2x speed and 3x multiplier or legendary skins can only be obtained by paying real money but I must say compared to other games you could say that this game is practically free to play but what helps the most are the events that come from every 2 months hopefully more frequent that are just so good.
