Plutonium

@Hercules2048 i don't know when i train a full spawn of zombies up i can make 3 or 4 thousand just off 24 i found myself quickly overpowered when buying upgraded galil ammo and mustang and sally than buying a new weapon from the box then packa punching it i think certain guns that are more op should have challenges completed like 300 headshots before the wall gun is buyable ya know some sort of challenge not like the rounds get hard until past 30
