Caster Turrent Upgrades

First Caster Upgrade

To get the initial upgrade for the caster traps, follow these steps:

Activate the Traps: Turn on the traps five times. The video suggests turning on all four traps in one rotation and then one more after the cool-down period.

Find a Hard Drive: After activating the traps, kill some zombies until one of them drops a hard drive.

Place the Hard Drive: Once you have the hard drive, place it in the machine.

Defend the Machine: Protect the machine from zombies while it is upgrading. The video recommends saving one zombie and stunning it repeatedly so it does not destroy the machine.

After this upgrade, the ether energy will no longer damage you.

Second Caster Upgrade

The second upgrade for the caster traps requires you to repeat a similar process:

Activate the Traps: Turn on the traps 10 more times.

Find and Place Hard Drive: Just like before, kill zombies to get a hard drive and place it in the machine.

Defend the Machine: Defend the machine from zombies during the upgrade.

Final Caster Upgrade

For the final upgrade, follow these steps:

Activate the Traps: Turn on the traps 15 more times.

Find and Place Hard Drive: Kill zombies to get the final hard drive and place it in the machine.

Defend the Machine: Defend the machine while it completes the final upgrade.

Upon completion of this final upgrade, the trap will be granted a Brain Rot ammo mod when it shoots at zombies.

This upgrade will increase the area of effect when you activate the traps.
