New Prototype Weapon: GPU-28 ORP

Attention, Airman!

When the horde has a clear path to the base, take it away and hold them back long enough to pulverize the wave from above.

Introducing the brand-new GPU-28 ORP Prototype Missile, built to freeze, divide, and control incoming zombies.

Its impact freezes every zombie in the area for 2 seconds, buying you time to line up your next strike. Cross-shaped rubble then breaks the horde into separate groups and forces survivors to find another route. Damaging geysers erupt around each divided zone, punishing zombies as they try to move forward again.

Refine the weapon to increase the geyser radius at MK3, then deploy 12 additional geysers at MK6.

Reshape their route, slow their advance, and keep the path to your base under control.
