Late military building from the May 23 update for sustained spider robot pressure.
The Technology Tree source now places Spider Base after the deep troop-damage path, with a $25B research cost and 48-hour unlock timer, so treat it as a true late-game pressure option.
Best used during the Late game when your next bottleneck matches the Military role.
Do not rush Spider Base from a weak economy; reach Mech Station first and keep tanks, air, or soldiers funded while the long research window finishes.
Use the planner after buying this structure to check whether the next upgrade should be economy, systems, or military pressure.
