I can't play just keeps telling me an unexpected error has occurred edit: I can't contact through in hame because it doesn't even load

★☆☆☆☆

p2w. multiple heros/c.o locked behind pay wall with not f2p option to obtain case and point t.pass purchasing the 12.99 premium pass is the only way to obtain one of the 6 c.o options available. c.o in question is named nukerilla. game play is pretty standard for this type of game very little stood out from other titles that follow this same formula.
