This game is a totally money pit,I've been playing on and off for years trying not to spend much money, took me over a year to get a 25"max" base just to have the developers change the heroes to where it's impossible to compete unless you spend, spend and, oh yeah, spend,,,no support team help whatsoever,,,,honestly,,,,I still play but it's become a time killer more than an enjoyable game, positive reviews =spenders, don't be fooled,they're full of 💩
