"DAWN OF THE DEAD"
This call took us to a cemetary.  Contrary to popular belief, most grave yards aren't haunted.  This one, was very haunted.  Swarms of spooks flew everywhere.  With defeat drawing near, they soon possessed various buried bodies.
Soon we were surounded by zombies.  Arms and heads were coming out of the ground everywhere.  One of our teammates almost got pulled under.
Luckily zombies aren't too hard to deal with.  Their slowness did them in against full-stream proton packs.
We heard they loosely based our little adventure on a recent summer movie.  Might have to check this one out.  Just remember, don't believe everything you see.
