Rantz Research

Choose what to research. Let Rantz Research handle the rest.

Rantz Research automatically selects your next technology based on your preferred strategy, science packs, and research limits.

Six research strategies: Fast, Slow, Cheap, Expensive, Balanced, and Random.
Science pack controls: Set each pack to On, Off, or Dynamic.
Dynamic availability: Monitor a lab and research technologies using selected packs only while those packs are available. Ideal for intermittent agricultural or promethium science deliveries.
Whitelist and blacklist: Control which technologies automatic research can select.
Infinite research limits: Set a target level for individual technologies. Once reached, research pauses for that technology until you raise the limit.
Flexible settings: Allow research switching, restrict selection to queued research, or deprioritize infinite technologies.
Compact interface: Collapsible sections remember your preferences, with research lists sorted by strategy and unavailable technologies greyed out.

Controls

Open the interface with Shift+T (customizable).

Dynamic Mode

To use Dynamic mode, open a lab, expand its Rantz Research panel, and select Monitor this lab. One lab is monitored per force. Pack checks default to every 10 seconds, with a 60-second grace period before an empty pack becomes unavailable; both timings are configurable.
