Upon landing, you'll need to find an entry point into the facility. Look for ventilation shafts or compromised structural points. The initial approach can often be done stealthily. Use your tactical equipment, such as sensor grenades, to mark enemy positions before engaging. If you have a suppressed weapon, use it to take down isolated enemies without alerting others. Avoid open confrontations if possible to conserve health and ammo.
Once inside, the facility will be a maze of corridors and industrial areas. Expect patrols and stationary guards. Use cover extensively and peek around corners cautiously. Some areas may have environmental hazards like exposed pipes or machinery; use these to your advantage by shooting them when enemies are nearby. Your objective is to reach the central data core, which will involve navigating through several enemy-infested sectors. Always check your corners and be ready for sudden engagements.
