Valley Pass Level 1 Auto-Defense Guide
- Set Two Gun Towers and Two Grenade Towers
- Add Facilities Near the Spawn Point
- Gun and Grenade Towers Get The Job Done
- Executioner Gains Increased DEF Below 50% HP
Set Two Gun Towers and Two Grenade Towers

Clearing Operator Intervention allows you to place one additional facility, so add one more Gun Tower.
Add Facilities Near the Spawn Point

In this stage, enemies spawn from a single location and have only one path of entry, so it's effective to place your facilities to block this route. Set up Grenade Towers and Gun Towers around the spawn point up to the maximum limit.
Gun and Grenade Towers Get the Job Done

Valley Pass Level 1 can be cleared using the Gun Tower and Grenade Tower, which can be unlocked early in the AIC Plan. The AoE Grenade Tower is strong against regular enemies, and the single-target Gun Tower is strong against bosses, so place a good balance of both to handle them.
More Grenade Towers Recommended
In many stages, multiple small enemies spawn simultaneously, and relying too heavily on Gun Towers may not eliminate them quickly enough. To maintain stability, prioritize deploying AoE Grenade Towers and focus your own attacks on high-HP enemies.
Executioner Gains Increased DEF Below 50% HP

The Bonekrusher Executioner's DEF significantly increases once its HP falls below 50%. It has a long wind-up animation, making it vulnerable to concentrated fire from multiple facilities.
Valley Pass Level 1 Operator Intervention Guide
- Set One Gun Tower and Two Grenade Towers
- Fight Near Your Combat Facilities
Set One Gun Tower and Two Grenade Towers

On your first attempt, you can place 3 combat facilities. Add your facilities near the enemy spawn point. By fighting near your combat facilities, you can reduce the number of enemies that slip by.
Fight Near Your Combat Facilities
When you hit an enemy that is heading towards your base, it will chase you for a short time. Therefore, by fighting near your combat facilities, you can keep enemies within their range for a longer period.
