5. After defeating the Axebeast, loot the nearby Red Nodule Shutter Box and Auto-Vendor to obtain a large number of Enigmatic Gold Bars and rare materials

6. Evacuate immediately to achieve high-yield resource farming in a short time

Key Routes & Efficient Farming in Aberrant Zone 4

1. Take the elevator, get the key, go up to the platform, then head west (left) to check the zipline (leads to the highway above the spawn point for round trips).

2. Turn east (right), go straight along the front-left path, defeat the guarding enemy to get the key and trigger the cutscene.

3. After the cutscene, head south (bottom), take the front-left zipline down. Land, go north (top), clear tent guards (use explosive barrels for ease), get the tent key and trigger the cutscene.

4. Head east (right) again, circle through containers to pick up the key and watch the cutscene.

5. Go north (top), take the elevator to the first floor, follow the mission tracker, get the key near the administrator and trigger the cutscene.

Key Routes & Efficient Farming in Aberrant Zone 5

*Note: Opening the backpack won’t increase pollution; bring explosives for resources and combat.

1. Go north to take the zipline, activate the flower lock frame westward, then take the 186m zipline eastward (unlock via Chest 4 first), and follow the mission tracker to clear monsters and enter the door after the cutscene.

2. Jump through the north and west platforms, go up the spiral staircase to get the first key; then open the lock eastward, jump over the northwest platform, trigger the mechanism to get the second key, and take the elevator northward to get the third key near the administrator.

4. Clear the northeast guarding monsters to get the fifth key, go north to take the west elevator up one floor, open the south yellow lock to get the sixth key, then challenge the final boss and collect its dropped materials.

5. Use explosives to destroy nearby mines to collect maximum resources before extracting; follow the mission tracker after extraction.

Key Routes & Efficient Farming in Aberrant Zone 6

Tip: Complete the main quest of Echoes of the Aberrant, then head straight to Zone 6 to fight the boss. Turn on the flame switch in advance; the boss will be instantly killed by the flamethrowers when it jumps onto the platform. Turn off the fire, collect the rewards and gold nuggets, and you can max out the gauge in about 20 minutes. Important tip: Remember to turn the flames back on after collecting rewards for easy repeated farming.

1. Go north to use the lock, head west to take the zipline rack, then go east to cross the 97m zipline (unlocked in the previous run). Proceed northeast to the elevator, go up to the first floor, then take the east zipline unlocked in Exploration Plan 5 and follow the mission tracker across the broken bridge.

2. After the cutscene, go south to find the 209m zipline near the spawn point for emergency re-entry if forced out. Head northwest to take another elevator to the first floor, then go north along the path to reach a second elevator and descend further.

3. Follow the mission tracker to fight the boss, collect its materials after defeating it, and proceed with the interaction to finish the cutscene.

4. Go northwest and climb three flights of stairs, then head southeast to activate the mechanism that will burn the boss if it re-approaches.

5. Use excess Disorder to mine the minerals under the stairs, gather all loots, then extract immediately to complete the mission.

*Note: Ensure you have completed Resistance 2 and Stability 9 first; the boss has extremely high HP and may force you out with insufficient damage.

Conclusion

The optimal gameplay strategy for Etchspace Salvage: Unlock shortcuts first → Target high-value loot → Avoid ineffective combat → Evacuate as early as possible → Repeat the commission cycle.

Advice for new players: Prioritize unlocking all Ziplines and Ropes, focus on farming Axebeast-related resources in Aberrant Zone 3, open high-tier Shutter Boxes, and accumulate Aurylene Crystals. This not only allows you to quickly advance the progress of Key Commissions and maximize Operation Metrics gain, but also efficiently farm endgame cultivation resources and gacha items.
