Mission 16 - Masks Off
After the cutscene you'll only have a simple SCARAB rifle with less than 100 bullets. Follow Tara and take the elevator. Mark the area with your visor, being sure to sneak or kill the Cell soldiers around the corner. Head to the top level and armor up. Kill the Cell guards at this level with your SCRAB or grab a GRENDEL from one of the fallen. The fight should be over quickly, as the Cell fighters will tend to throw grenades at their own feet.
Head into Hargreave's office and use the syringe on the table. After the scene, ignore the Ceph intruders head south and charge towards the objective marker. Turn on armor and walk along the crates and pipes to avoid the electrically shocked ground. Exit out the roof and grab the GAUSS rifle on the ground. Descend to the street level and move south-east, staying either cloaked or armored to deal with the Ceph forces. After sneaking to the next goal, be sure to restock ammo and grab any guns off the dead Cell members.
Head under the gate to reach the next objective marker. Sneak by the Ceph heavies and huge amount of ground troops. Enter the two lifts to make it to the highway. Arm yourself with the X-43 MIKE and help Cell take out the Ceph aliens. Heed Gould's advice and leave the Ceph to the Cell forces. Cloak and run across the bridge. Hit the onscreen buttons to keep from falling, which will soon conclude the mission.
