Tips

Resource Management

Royal Jelly is essential for evolution. Plan your evolution path carefully based on available resources.

Host Rarity

Some hosts like Engineers and Predators are rare. Save special eggs until you have the appropriate host available.

Special Requirements

Some pathways have unique requirements - the Protomorph pathway doesn't need a host, while the Jockey pathway requires rare event captures.
