The Overclocked CPU is an uncommon Equip Item awarded occasionaly (5% chance) by destroying machine-type blimps. It can also be bought at the Item Shop for 150 MM. It can only be equiped to machine-type and cyborg-type towers. When done, it increases their fire-rate by 20%, popping power by 100% and reduces ability cooldown time by 15%. The downside is that there is a 75% chance of a machine overheating every 30 seconds, dealing 2 HP damage to itself and stunning it for 5 seconds.
