Universe FAQ
Can I play several universes?
Yes, you can create a separate character in each universe and switch between them. Progress in each universe is saved independently.
Are my achievements saved when I move to another universe?
Each universe has its own progress. Achievements and resources do not carry over between universes, but your global player profile is shared.
How do the universes differ besides game pace?
Can I transfer resources or fleet between universes?
No, each universe is fully isolated. This ensures fair play and equal starting conditions for everyone.
How do I choose a universe if I am unsure?
Start with War of Alliances — the flagship with the best onboarding, the most polished PvE and apps for iOS and Android. You can try Classic and Reborn later on the same account.
Does the premium account work across all universes?
Yes. One premium covers all three universes at once. This is so you can try different styles without paying twice.
