[X] Plan Spider's Electric Web
-[X] Take the Electric Baton. See if you can find any not spilled drink close nearby.
-[X] Let the Psycho come close, staying as close to the pillar or any cover you can find.
-[X] When he's close enough, throw the drink and attack with the baton, aiming for Chrome parts, especially the head/eyes or the malfunctioning arm.
-[X] Once he's stunned, kick the gun out of his hand, then go grab it!
--[X] If you manage to get the gun, focus on getting the distance from him. Take some shots at him if you get enough distance.
--[X] If he still has the gun, try to stun him some more, or get into cover if you lose the baton.
