I don't regret much in life but I regret ever playing this game. Spending $50 doesn't even fully unlock a hero. Try more like $1000, that's not a joke. Best heros in the game are $10,000+. Again, no joke. Playing this game has been one the worse gaming decisions I've ever made. Please stay away from this ponzi scheme. This game is trash and the developers only care about scamming you out of money.
