Crawler

Crawler

Class Bonus

Any player class can build Crawlers. The Collector class gets a ×1.5 active cap bonus (more Crawlers count as productive).

Overview

The Crawler is a surface mining drone that boosts the production of the three mines. Each Crawler has a small but cumulative effect on Metal Mine, Crystal Mine, and Deuterium Synthesizer output. However, they consume energy.

Requirements

Production Bonus

Each Crawler provides a small mining bonus. The bonus per Crawler scales with the mine levels and is subject to a maximum cap per planet.

Active Crawlers=(Metal Mine+Crystal Mine+Deut Synthesizer)×8\text{Active Crawlers} = \left(\text{Metal Mine} + \text{Crystal Mine} + \text{Deut Synthesizer}\right) \times 8

The Collector class raises this cap by 50%:

Active Crawlers (Collector)=(Metal Mine+Crystal Mine+Deut Synthesizer)×8×1.5\text{Active Crawlers (Collector)} = \left(\text{Metal Mine} + \text{Crystal Mine} + \text{Deut Synthesizer}\right) \times 8 \times 1.5

Crawlers beyond the active cap exist but produce nothing and still consume energy.

Diminishing Returns

Crawlers beyond the maximum effective count provide no additional bonus. Match Crawler count to your cap.

Base Boost per Crawler
  • Metal Mine: +0.0002 production per unit per mine level
  • Crystal Mine: +0.0002 production per unit
  • Deuterium Synthesizer: +0.0002 production per unit

Energy Consumption

Crawlers consume energy. Each active Crawler uses 50 energy. Their economic benefit must be weighed against the energy cost of powering them.

Tips

Late Game Only

Crawlers are a marginal gain — most useful on well-developed planets with mine levels 30+. Early game, those resources are better spent on mines directly.

Keep Them Defended

Like Solar Satellites, Crawlers are ships and can be destroyed in battle. They live on the planet surface but are vulnerable to attacks.

Alliance Tax

Some servers give alliance members a production bonus. Crawlers stack with this.
