Hold the line!

You and your squad have been tasked with holding a **** hold point that is the most **** entrance point to a civilian housing base. You must hold the **** hold for long enough for the military to evacuate the civilians.

The **** hold is basically a canyon with a few overhead bases and a few walls. with turrets attached. the entrance is a sheer cliff that goes on and around for kilometers creating a natural wall around the civil base.
