4 Recommended Defense Plans
- Zone Alerts: Use radio relays to set up alarms around base perimeter, lock onto spawn points 10 seconds in advance.
- Funnel-type Fencing: Guide enemies to concentrated fire zones, reserve 2 blocks width on each side to prevent explosion friendly fire.
- Energy Shield Walls: Highly effective against ORDER ranged squads and IS-0307 laser units.
- Elemental Trap Combinations:
- Fire mines vs Ramogi, zombies
- Electromagnetic pulse vs mechanical systems
- Freeze vents vs Canaan rioters
- Multi-layer Backup Power: Ensure continuous power supply for beacons, suppression fields, and defense towers.
