don't know what you guys are salty about.
been playing for a month now, don't even have my 5th spot in hangar unlocked because spent gold on bot and weapons and i evolved nicely without spending any cash.
the bought bots and weapons give a serious challenge but i put them in the scrapyard regularly with my oldschool bots and weapons.
if you don't want to spend money you spend time, that's how it is.
also, developing these games and running the servers is not cheap so it's no more than logical that the company behind this game wants to get payed.
