MACHINE ATTACKS #1 THE PREMIUM UPGRADEBefore I write this tutorial, then sorry about my englishI see everyone has a problem with this premium upgrade at machine attacks sometime they will lose their upgrades all, but sometime they will lose some upgradehere, I will teach you how to use a premium upgradeAvoid to lose all upgrades Do not re-join and change class if the game has begunDo not change weapons if the game has begunTry to avoid to refuse the upgrade if it isn't nescessoryBut if it's nescessory to refuse the upgrade, follow this1)if you use normal upgrade which part, you should refuse that upgrade with a normal, do not use premium to refuse2)if you use premium upgrade which part, you should refuse that upgrade with a premium, do not use normal to refuseHow to upgrade by fair priceFor defensive upgrade, try to not upgrade all defensive, you should upgrade bullet,fire,blast resistance on the normal upgrade for half each of them, then upgrade DMG all source resist ,heal from pack,life regen for half each of themIf you confront with robots which is high DMG that can kill you instantly, you need to remember which type of dmg , and go to premium upgrade and buy power canteen 100% resistance which type of dmg to against themIf you want to upgrade a fire speed or a reload speed, you should upgrade from normal upgrade because they are fair price, when it's max so switch to premium upgrade and upgrade them to become ultimateWarning!, if you keep to upgrade fire speed and reload speed, because they will waste your ammo so much, cause you need to upgrade max ammo or max clipsize and waste your money more, I suggest should upgrade damage and ammo regen insteadIf a premium button or normal button dosen't change after be hitthis will happen everytime when you restart a mapto solve this, shoot at premium upgrade button even if it's green light, then wait for 5 seconds and shoot to normal upgrade again
