Updates the Alien Staff Patch to v1.2. (Requires the first Alien Staff Patch.) Adds better sound for the hit, reworks the frames a bit, and adds a physics model. There's still no second trigger.
Adds a spent shell casing to the firing sequence with the M1 pistol. The M2 and Infinity pistols have this... why not M1? No sound patch, so you can't hear it hitting the ground.
