The mecha spine crawler was a Mecha Swarm structure created by Egon Stetmann during the End War. It served as an anti-ground base defense for his hive clusters, functioning similar to the zerg spine crawler in most regards.
The mecha spine crawler is a anti-ground defensive structure available to Egon Stetmann in Co-op Missions. It functions much the same as a normal spine crawler, though mechanical and with a faster movement speed when unburrowed. Mecha spine crawlers can be made and root outside of creep and egonergy fields.
Crawlers can uproot themselves and move about, and can plant themselves back down on any location. Crawlers cannot attack while uprooted.
