F.E.A.R. 3

The level is called Port. It starts with you outside an airport while you continue your pursuit of Becket. The level introduces Scavangers (odd dog like creatures that turn orange as they take damage), they are fast, agile and powerful in numbers (they can easily be killed by slowing time down when the jump and back stabbing them).

Most of the level is straight forward, you'll deal with Scavangers, Soldiers and, at multiple points, Phase Casters and Phase Commanders (easily identifiable by the blue shield around them). It's best to use Shock Grenades on them, they stun (allowing you to use whatever weapons you want) and cause small amounts of damage. If you're playing as Fettel, you can posses one when the shield is down (they'll glow red).

At one point, you'll have to fight 2 Phase Commanders at once after a wave of Soldiers (I believe it's shortly after the helicopter crashes and visions of the Creep begin). Here there are several G3A3 AR (I believe that's the name) in the back, these are very powerful (I suggest taking them for a future battle against Scavangers).

You'll end up in a garage like area at one point, and after opening a garage door, Scavangers begin pouring in through portals. Instead of running into the room that the door is blocking, stay in the area where they spawn, mainly due to the size difference. The area beyond the door is very cramped, and you'll take a lot of hits on higher difficulties.

After that part, you're basically in the clear. Any questions, or things you'd like to add, leave a comment and I'll add it.
