R1: I'm screwed, and I only have a pillow. 0/10

R2: Trap him in my basement using a shitton of fire and gasoline, while blocking the doors with computers and pouring sand down the laundry chute. I might win, but he's probably getting out. 3-4/10

R3: Placement. I distract Batman when he gets close, get the tear gas to go off when he comes near me, time the other guns besides the sniper rifle to Hellzone Batman, shoot Batman near the heart with the sniper ridle, then stab his heart to make sure he's dead.

...or that's what I want to happen. More likely, I shoot at him, he comes near me, I try to stab him, and I fail. 0/10

R4: I hijack a CTA train car, and Batman does so too at Linden. A duel proceeds down the Purple Line and through Evanston, as I keep trying to shoot Batman himself. Eventually, either me or him gets the idea of shooting the car's wheel, causing the car to derail and fall into the streets. 5/10

R5: I get fucked up. 0/10

R6: Same as R4, but we manage to get off on Howard, where we keep fighting. I eventually tire, or incapacitate Batman. 5/10
