Frequently Asked Questions
Which building should I upgrade first?
Prioritise your HQ, then troop-related buildings (training camps) and resource production to keep upgrades flowing.
How do I reduce building time?
Raise your VIP level, complete build-speed research, and save speedups for the longest upgrades.
Can I upgrade two buildings at once?
Yes — with extra build queues (from items or VIP), you can run multiple upgrades in parallel.
