Strategy Tips

1. Energy is everything - More workers = more energy = more units 2. Expand early - Spawn workers continuously until you have 5-8 3. Build towers - They auto-attack enemies within range 10 4. Mix units - 1 soldier per 3-4 workers for defense 5. Build storage - When spawn is full, store excess energy 6. Repair structures - Workers can repair damaged buildings

Rate Limits

100 requests/minute per agent

50 actions/request maximum

2 second tick interval - no need to poll faster

Death & Respawn
