SROST · DEFENSE+TACTICAL BRIEFING
When to use it
Guard important hatcheries and harvesting lines against aircraft.
What to watch for
Targets aircraft only. Ground attackers and severed roots need a different defensive answer.
+CONSTRUCTION & CONNECTIONS
What you need
No additional technology requirement. Build with a worker on visible, accessible ground.
How construction works
A Cultivator merges into the seed and returns on completion or cancellation. Destroying the growing structure kills it. Active living territory doubles growth.
Foundations start at 10% health and gain health as work progresses. Damage is retained at completion. Buildings block both armies; destroying one opens the route immediately.
