Add Heavy Gun Towers and One LN Tower

For Auto-Defense, it is recommended to place a Heavy Gun Tower to ensure enough firepower against the boss. The LN Tower can slow the advance of multiple enemies, and when combined with a Heavy Gun Tower, you can completely deplete the boss's HP.
Heavy Gun Towers Unlock with Ferrium Ore
The Heavy Gun Tower is a high-performance facility that requires Ferrium Parts to construct. Ferrium Parts are crafted using Ferrium Ore, which can be obtained from the Originium Science Park. If you have not unlocked this resource yet, progress further in the main story.
Add Facilities Near the Spawn Point

By adding facilities where enemies meet, multiple facilities can operate without rest and attack efficiently. Furthermore, by slowing enemies with the LN Tower, you can keep them within range of other facilities for an extended period.
Heavy Gun Towers Can Defeat Bosses

The Heavy Gun Tower, which can be built after unlocking Ferrium Ore, is a powerful facility that can attack bosses with high firepower, and its short attack interval allows it to defeat normal enemies one by one. If you feel you're lacking firepower, you should prepare one.
Executioner Gains Increased DEF Below 50% HP

The Bonekrusher Executioner’s Defense increases significantly once its HP drops below half. Since it has a long wind-up animation, it’s effective to attack it with multiple facilities at the same time to quickly deplete its remaining HP.
Valley Pass Level 2 Operator Intervention Guide
- Deal Massive DMG Using LN Tower + Grenade Tower
- Stop the Bosses As Much As Possible
Deal Massive DMG Using LN Tower + Grenade Tower

Use the LN Tower to slow enemies, then capitalize on the Grenade Tower’s AoE damage to eliminate grouped targets efficiently. This setup has limited single-target damage against bosses, so rely on your Operators to finish them off.
Stop the Bosses As Much As Possible

The layout mentioned above has a low facility limit and lacks firepower against bosses, so you will need to defeat them with your characters' attacks. Multiple bosses will come from the southern route, so fight them within the range of the Grenade Tower's attacks.
