You were taking cover behind a wall. Ghost was on the other side of the road under cover as well. There were few left.

Ghost was taking them out one by one, along with you taking a couple out.

However, you see a huge spider right next to your face and you jump out, revealing yourself to the enemy and almost getting killed!

Fortunately, Ghost got the last of them before anything could happen, but he was p!ssed...

"What were you thinking!" he yells at you once you all return back to base.
