I have been playing since beta. It is a Massive pay wall. EVERYTHING, yes everything is hidden behind in app purchases. Anniversary chests locked and need to purchase keys to open. Heroes and guns locked behind 20k+ diamond roulette wheel scam(each spin increases in cost best item always last). Certain features are fun such as combat simulation, bosses. Pvp favors pay2win heroes and guns. I do not recommend the game in current state. Everything needs to be made available outside of purchases.
