If you're tackling the Aburrey Quarry mission in Arknights: Endfield, it's essential to focus on both strategy and resource management to efficiently complete the 176/185 objectives. Based on my experience playing through Valley IV, one of the key challenges is positioning your operators effectively to handle the waves of enemies while conserving DP (deployment points). Ensure you start by deploying operators with crowd control abilities near choke points to slow down enemies, giving ranged units time to inflict damage safely. Deploying a medic or healing unit soon after can keep frontline operators alive longer during extended engagements. Additionally, be mindful of the mission timing and read enemy movement patterns; this helps in timing your rotations and deploying reinforcements before overwhelmed. Collecting resources scattered throughout the Aburrey Quarry area can significantly boost your operator development and overall progress. Don't overlook side objectives or smaller fights as these often yield EXP and materials needed for upgrading your roster. Lastly, join community forums and hashtag discussions like #ZerothDirective and #ArknightsEndfield to exchange tips and stay updated on mission patches or event changes. Collaborating and learning from other players' strategies can greatly enhance your gameplay experience and ensure you clear missions like 176/185 with ease.
