When it comes to farming loot efficiently in Arc Raiders, knowing the key locations and understanding your inventory management makes all the difference. For example, the Seed Vault Airshaft at 13m and 14m depth are hot spots where high-value items tend to spawn. It’s crucial to stay aware of the time limit, as the warning "Last warning: 2 minutes left, head back immediately" indicates you need to secure your loot and exit before the mission ends. Another tip I've found helpful is managing your encumbrance carefully—being "OVER-ENCUMBERED" can slow you down and make extraction risky. Prioritize picking up rare items like the LMG Torrente IV, which offers a large ammo capacity and high accuracy when crouched, enhancing your combat effectiveness while looting. Don't forget to make use of the upgrade modifiers and salvage system. Items with "45% Reduced Reload Time" or "5% Reduced Speed" can significantly impact your performance. Splitting stacks and dropping less useful gear can also free up backpack space for more valuable finds. Engaging with the map, logbook, and system effectively allows better waypoint usage and quick decision-making in navigating complex areas like the Atrium or Archives sectors. Staying adaptive and combining these strategies has improved my loot runs dramatically, making each expedition in Arc Raiders more rewarding and fun.
