The Combine had built a secret underground base (Omega Base) in the far reaches of Europe in the late 21st century. The base was used for many things like 'Zombie' tests, combat training and storage space. Sadly All hell is breaking lose! We need you to go in and 'Calm the Situation Down' by any means necessary! There are some rumors that the combine had built the base for a sort of home to all of their troops. It is said that the combine have figured out how to get sections of the world above and re-create them in their base! These are all rumors, remember that! You will need to keep a calm head because anything could be down there!
