Do not expect to play "contra" - this game hardly resembles the original. It's pay to compete (you can "win" the campaign without even trying, but locked by account level)... It inevitably becomes a terribly repetitive and boring grind. Sacrifices skill or challenge - to payment or simple grind. It requires 3gb of storage, to play the SAME 2-D maps every time?! Became too repetitive, same issue of tons of different currencies, terrible monetization, sneaky gacha. Awful game, already dying. Avoid
