Mission 2 - Sudden Impact
Head into the room in the east and equip your murderous paws with a new MARSHALL shotgun. Proceed ahead and after a brief scene you'll find yourself on the street. Head down the road and into the parking garage on the left. Climb up each ramp and fight the enemies inside. They will often get trapped on one another and unable to fight back, making them easy targets to stealth kills.
Grab a Stealth SCARAB from the stairwell and travel to the top to gain some collectible car keys. Tag the enemies with your visor and head below to kill them. Check the two wreckage pods on the north and west ends. When ready, head below and you'll get another call from Gould. Grab the JAW rocket launcher and destroy the Cell helicopter above. Continue following the objective marker to enter an elevator shaft. Drop down and you'll enter the dirty waters below.
Move up to the higher level and scan the biomatter with your visor. Exit out through the window and the aliens will start to attack. Due to the amount of dust you may want to consider turning on nanovision to catch their heat signatures. Kill at least one of these new alien enemies to gain nano catalyst which can be used to upgrade modules.
Travel under the bridge and kill any Cell troops and aliens along the way. You can also sit back and let the two enemy forces battle each other out, leaving you to simply pick off any survivors of the onslaught. Move through the last passage on the left and up the stairs to complete the mission.
