Security Guards are enemies in Fear Effect 2: Retro Helix. They patrol the Wing Chune Sculpture Garden during the Christmas Party.
The Security Guards roam the Sculpture Garden in front of the Wing Chune party. They only carry pistols but make up for it with their large numbers. Fortunately they patrol simple routes and their movements are predictable.
Do your best to sneak up on guards that you can kill with one shot but always be ready to pull out dual weapons when multiple Security Guards show up in the area. The Dual Uzis work very well against them.
