<1000SPM, 2-4 players - Silver: Mid game, 1000-5000 SPM, 4-8 players

SPM = Science Packs per Minute
Can I run experimental builds?
Yes! Change version in server settings:
- Stable - Latest stable release (recommended)

Note: Clients must match server version to join.
How do I create a death world?
Configure for maximum difficulty:
- Set enemy size to "very big"
- Set enemy frequency to "very high"
- Set evolution factor to max
- Enable pollution spreading
- Reduce resource richness to minimum
- Enable biter expansion
Death world is brutal - prepare defenses early!
Why is my server lagging?
Common performance issues:
- Complex logistics - Reduce active bots

- Massive factories - Upgrade to Gold plan
- Mod conflicts - Disable problematic mods

For mega bases (10k+ SPM), use the Gold plan.

Or install PvP-focused mods like "Oarc Multiplayer Spawn".
