Your next task is to activate a power grid to access deeper parts of Sloan's facility. This will involve navigating through a heavily guarded area. Expect more resistance than in the previous mission. You'll encounter new enemy types, potentially including shotgunners or armored soldiers. Utilize cover effectively and aim for headshots. If you have grenades, now is a good time to use them against clustered enemies.
The power grid activation point will be marked on your HUD. It might require you to interact with multiple consoles or switches in a specific sequence. Be prepared for enemies to swarm the area once you begin the activation process. Consider setting up traps with C4 (if you've acquired it) or finding a good defensive position before initiating the sequence. Once the power is on, a new path will open, leading you further into the facility.
