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.
