On hearing some little kids shouting, Martinez starts to run. Sounds like there's some kind of animal, but a nasty one. Well-drilled hands the canister of OC spray from his belt, raising it to eye level as he approaches the alley.
The animal is not any Martinez has ever seen before, but adrenaline and training have taken over. He'll have time to question his reality later. As the creature approaches, he sends a long stream towards its face. He only succeeds in making it mad. The monster swipes at him, and he narrowly dodges. Its claws are the size of large knives. Martinez drops the pepper spray, and for the first time in the field, draws his firearm.
Martinez fires three shots. Three 9mm hollow-point bullets rip into the monster's body: at this distance, he can't miss. The monster keeps coming, and this time its claws connect. Martinez drops to the ground with a gasp, two long gashes across his torso. He's lucky: if not for his stab-proof vest, the Chasm Beast would have disembowelled him with a single stroke. As it stands, his wounds are very painful, but not immediately fatal.
He raises his gun, but the monster swings for his hand. The claws narrowly miss, but the paw hits him. His gun slides across the alleyway... stopping between Emily and Concordia.
