Projectile-heavy defense shooting Mow down light enemies with sustained machine-gun fire, blast armored targets with rockets, and stop close-range threats with powerful shotgun bursts. When the swarm becomes too dense, call in artillery support and cover the battlefield in explosions.

Combine your own weapons with support fire to create a wall of bullets, shells, and explosions against the incoming horde.

Lina "What are you looking at? Never seen a genius fix a cannon before? Keep talking nonsense and I'll stuff you in the barrel and fire you out!"

Don't wake me unless the base explodes." A lazy but brilliant scientist whose automated turrets are far more dangerous than her attitude suggests.
