How to Clear Chapter 21 Blue Ridge Quarry in The Walking Dead: Aftermath

To clear Chapter 21 Blue Ridge Quarry in The Walking Dead: Aftermath, you must immediately break a two-angle sniper crossfire upon entering the map. The encounter places your squad in the direct sightline of two elevated watchtowers: one straight ahead and one on the elevated ridge to your right.

Dismantle the frontal watchtower first while staying behind entry cover to break line of sight with the right side, clear the incoming walkers, and then push the right ridge to take down the second tower.

Tower Threat Breakdown

Advancing straight into the quarry floor exposes your survivors to overlapping fire from both gunners, who outrange standard riflemen.

Step-by-Step Tower Elimination Sequence

Follow this order to prevent your squad from getting pinned down by crossfire:

1. Hold near the entrance cover: Do not advance past the initial rock formations. Position your squad so that natural outcroppings block the line of sight from the right-ridge tower while keeping the center tower targetable.
2. Burn down the frontal tower: Focus your ranged survivors on the center watchtower. Have your frontline tanks trigger defensive shields or mitigation buffs to absorb the opening sniper rounds.
3. Clear drawn walkers in place: Gunfire attracts patrolling walkers at the base of the tower. Hold your ground and eliminate this pack before moving forward; pushing ahead with aggroed enemies on your heels will trap your damage dealers.
4. Advance up the right ridge: Once the entry lane is clear, swing your entire squad toward the right slope. Use the rising terrain to close the distance and eliminate the secondary tower before the gunner inflicts heavy attrition.

Pathing and Chokepoint Management

Avoid cutting directly across the open quarry basin. While the center floor offers direct paths, it lacks defensive cover and leaves your squad vulnerable to lingering hostiles.

• Hug the outer boundary: Move along the left quarry wall when navigating deeper into the stage. The perimeter rock formations block elevated sightlines and funnel ground enemies into tight lanes.
• Leash enemies to cleared ground: When engaging walker patrols around mining equipment, pull back toward areas you have already cleared. Rushing forward into uncleared territory risks pulling additional patrol groups and exposing your team to unexpected ambushes.
• Maintain squad spacing: Keep support units close enough to provide aura buffs and healing without grouping so tightly that melee swarms can pin the entire squad at once.

Ability Management and Extraction

Proper skill timing ensures your squad has enough burst damage to handle both fortified structures:

• Save burst skills for structures: Use basic attacks and secondary abilities to finish off weak walker swarms. Reserve your highest single-target damage skills for dismantling the tower structures quickly.
• Stagger cooldowns across both towers: Do not expend all offensive ultimate abilities on the first tower. Save substantial burst damage to quickly eliminate the right-ridge fortification when you initiate the second push.
• Stabilize before final extraction: After both towers fall, systematically sweep the remaining walker clusters around the heavy machinery and mining pits. Allow squad health regeneration mechanics to recover damaged survivors before approaching the final extraction zone. Proceed cautiously around abandoned quarry carts and containers to avoid late ambushes.
