Ambush him

You risk a peek over the edge of the pallet racks, spotting Eddie working his way down the aisle. As you quietly pull your box of screws close, ready to drop them, Eddie approaches the mess you left on the floor. He looks down at the scattered screws and bolts, studying them, before you hear a slight grunt. "I know you're up th--." He cuts off mid-sentence as your box of screws slams into his shoulder, dropping him to the floor with a grunt, followed by a crack as his skull bounces off the concrete. The pistol falls from his hand, skittering away a few feet, coming to rest in the center of the aisle. Before he's even hit the floor, you're scrambling down the racks, watching in case Eddie isn't completely done.

As your toes touch the cold concrete again, you turn towards the pistol, mindful of the screws. Carefully, you step over to the pistol, footsteps nearly silent against the floor. As you grab the pistol, Eddie groans again, then hollers in pain, before a hissed "Bitch." slips through his lips. You spin, pistol raised, to find Eddie starting to sit up, back towards you, pulling a screw from where it had embedded in his arm. You can see dozens of them poking out from various other points on his back and arms.

You immediately raise your pistol, drawing a bead on Eddie's head, and pull the trigger, only to be met with a muted click as the hammer falls on an empty chamber. The fat fuck had shot the entire magazine at you, and hadn't brought a spare mag. Shit. Eddie turns toward you, a slight grin on his face, beneath unfocused eyes. "Can't shoot me with no ammo, can you, bitch? Drop the gun. Last chance." As he says this, he starts to reach behind his back.

Your mind flashes into overdrive, time seeming to slow as options fly through your head. He much bigger and stronger than you. If you go for the kill, it will have to be done fast, before he can react. The only advantage you have there is that Eddie still seems rather dazed from his head bouncing off the concrete floor. The only other option is to flee again, hoping that his injuries slow him enough for you to either find a weapon or just outright escape.
