Update.... I'd give it less than a one star if I could. I have WASTED over a year playing this BS game. It's a game based on PVP and your opponent ALWAYS gets the advantage AND always gets boosts faster. Even if you have the same heros. Reviving heros will always come back, and will come back with boosts loaded. Complete BS. It's a joke of a game. Don't waste your time or money this game is not worth it. And any review saying otherwise is a lie.
