1. Focus on destroying higher-value enemies first (top rows)
2. Use Rapid Fire sparingly to conserve points
3. Activate Overdraft only when necessary
4. Buy additional agents when you have surplus points
5. Save your NUKE for when truly overwhelmed
6. Each mission level increases enemy speed and fire rate
