Own a SPAS-12 for home defense, since that's what the rebels intended. Four Civil Protection units break into my house. "What the devil?" As I grab my rebel issued beanie and SPAS-12. RMB on the first man, he's dead on the spot. Draw my AR-2 on the second man, miss him entirely because the energy ball bounces off the walls and nails the neighbors antlion. I have to resort to the tau cannon mounted at the top of the stairs loaded with depleted uranium-235, "Tally ho lads" the beam shreds two units in the blast, the sound and extra shrapnel set off car alarms. Grab a crowbar and charge the last terrified cop. He Bleeds out waiting on reinforcements to arrive since crowbar wounds are impossible to stitch up. Just as Gordon Freeman intended.
