Editing Circuit (Hardcore) (section)

==Strategy==
This strategy refers to the state of the game while the '''Invisible''' still appeared in the [[Hardcore Mode|Hardcore]] mode.
*This enemy must be defeated quickly. If not, it can speed enemies up to speeds greater than the [[Glitch]] and [[Fallen Rusher (Legacy)|Fallen Rusher]].
**This can speed up large enemies, such as the [[Slow King (Legacy)|Slow King]] and [[Vindicator (Legacy)|Vindicator]], and even major bosses like the [[Fallen King (Legacy)|Fallen King]]. Taking into account the ability to stack, this has the potential to be the most dangerous enemy in the game.
*Fast-firing towers, such as the [[Minigunner]], paired with the [[Commander]], are recommended to defeat the '''Circuit''' quickly.
**Long range towers, like the [[Ranger]], are also recommended.
**The [[Accelerator]] is not recommended against the '''Circuit''' as it will likely get out of its range before the [[Accelerator]] can charge up.
***Not to mention when the [[Accelerator]] targets an enemy it will not change targets before the enemy is killed, which may cause the '''Circuit''' to slip by.
***You can counter this by slowing down the '''Circuit''' with the [[Frost Blaster]], [[Toxic Gunner]], [[Sledger]], [[Harvester]] or [[Freezer]] to allow your [[Accelerator]]s to charge up and attack it.
*The [[Rocketeer]] and [[Mortar]] can damage hordes of '''Circuits'''. However, be aware that the '''Circuit''' may outrun the projectiles from these towers.
*The [[Electroshocker]], [[Toxic Gunner]], [[Sledger]], [[Harvester]] and [[Warden]] can be used to slow down the '''Circuit'''.
**Do note that the [[Stun Immunity]] that the '''Circuit''' has prevents stunning towers like the [[Electroshocker]] from stunning it, with it only being slowed down instead and it cannot be knocked back because of it.
*The [[Military Base]]'s [[Tank (Unit)|Tank]] and [[Railgun Tank]] are the best in halting the advance of the '''Circuit''' as it can easily sprint past all of your defenses.
