Overclock

What it is

Overclock is a temporary emergency boost: every defence gains +50% damage and +50% fire rate for 25 seconds. The catch is that it costs 25% of your board’s total value.

How to use it

• Find the Overclock button on the right-hand column (under Build & Perks).
• The button shows the live cost before you press it, then the remaining seconds while active.

Pro tips

This is a panic button, not a buff — save it for the wave that’s about to breach the door. Combined with a SUPER and a few synergies, 25 seconds of overclock can turn a doomed wave around.
