To beat Chapter 17 in The Walking Dead: Aftermath, anchor your defense along the upper-right riverbank by constructing an early Gunner Tower and using the Scavenger Magnet to collect dropped supplies. The river acts as a natural barrier that funnels incoming walker waves into a narrow crossing channel. This setup lets your automated defense and ranged survivors focus fire along a single path without exposing your squad to multi-directional ambushes.
Riverbank Gunner Tower Placement
Placing your Gunner Tower along the northeast waterway secures a strong terrain advantage over open-field construction. The water restricts enemy pathing, ensuring incoming swarms enter the tower's firing arc in a tight, predictable column.
| Tactical Consideration | Open-Ground Placement | Upper-Right Riverbank Placement |
|---|---|---|
| Field of Fire Coverage | Spreads across multiple angles, diluting damage | Concentrates squarely down the narrow river crossing |
| Walker Aggression Draw | Exposes the structure to flanking and blind spots | Sheltered by water, forcing frontal engagement only |
| Squad Positioning | Forces survivors to split up to cover exposed flanks | Allows survivors to tuck safely behind the tower |
| Target Saturation | Results in weak single-target hits on dispersed swarms | Delivers sustained damage against compressed walker lines |
Building the Gunner Tower early eliminates initial scouts without burning squad cooldowns. In later waves, the structure absorbs frontal aggro, giving your survivors time to cycle abilities safely.
Step-by-Step Defense and Magnet Execution
To maintain your perimeter and collect resources without taking unnecessary damage, follow this sequence:
- Establish the Riverbank Choke Point: Build your Gunner Tower immediately at the upper-right water boundary before the first major wave crosses the river.
- Form a Defensive Pocket: Station your squad directly behind the tower. Keep ranged damage dealers aligned with the water crossing, and hold frontline units in reserve to intercept any armored walkers or sprinters that slip through.
- Lock Down Elites at the Bottleneck: When an elite walker reaches the riverbank, apply crowd-control abilities to stall the target within the Gunner Tower's firing line so automated and squad attacks can focus it down together.
- Trigger the Scavenger Magnet After Horde Wipes: Wait until a large wave is completely eliminated before activating the Scavenger Magnet. Activating it between waves pulls all dropped scrap and ammunition directly to your position, avoiding the fatal risk of sending survivors across the river to gather loot manually.
Critical Mistakes to Avoid
A run on Chapter 17 can unravel quickly if you break your defensive formation. Watch out for these common failure points:
- Building in the Center: Placing a Gunner Tower in the open middle of the map invites attacks from all sides, splitting tower damage and leaving backline survivors exposed.
- Manual Scavenging: Running across the riverbed to pick up items manually leaves your squad down a combatant right as the next wave begins crossing.
- Overextending Past the Tower: Pushing forward into the water spreads out enemy aggro and prevents the Gunner Tower from serving as your primary frontline shield.
