To begin with this is a Guide for the Category "Beat the Game (Co-Op/Solo)"

The optimal RNG Boss Order should look like this :

• Eternal Star (The Skytemple Stage can Kill your run Really Really Quick, thanks to the environmental Hazards)

• Kur (Same reason as Enternal Star)

• The Perforator (Eventough you have already Killed Kur take his Weapon because it doesn't trigger i-frames, will be useful later on)

• Twin Astrals (if get them on higher levels you will have to play an Anoying "Dodge the Bullets game")

• Rollster (Astrals weapon is super Powerful angainst him)

• Death_Lotus (Use the "Gattlin gun" and D-Boost if goes in to his "Turtle Stance" since he does not Spawn any Plant minions anymore)

• Vile Visage (Always try to Hit his Weakspot)

• Shatterbreak (no threat at all xD)
