Billy vs Rat King
What's giving you trouble?
Full matchup plan
Mid game · Walkers
Use Bashdown and melee attacks against Royal Pestments; its bullet reflection does not apply to them. Blasted restores ammo with melee hits, leaving you ready to shoot when the barrier breaks.
Late game · Patron
Use Chain Gang when your team is ready to attack the enemies around the banner. Keep Rat King in sight until Chain Gang pulls him toward you, then hit him and nearby enemies with Bashdown.
