To defeat Scorpian a little easily,ignore the henchmen and collect the web cadridges on Race to the Bugle,then when you face Scorpian,hit him until he retreats to the next room.

Then,stay in the room you began in and start targeting and shooting impact webs.Then,when he has hardly any health left,put on web gloves and punch his lights out.

(He should face you when you shoot your impacts).
