Tactical Tips
- 1.Disable Self-Repair Protocol as your first objective — assign a fast stealth ship to breach the repair emitter.
- 2.Alien Beam targets the player with the highest aggro; rotate your frontline every 20% HP threshold.
- 3.50 Alien Fighters spawn simultaneously — spread your anti-fighter frigates evenly around the flagship's perimeter.
