From memory these are the steps I remember. Here’s how I did my runs anyways

• Complete 3 challenges - get rewards
• build shield
• PaP open
• Find skull
• Shoot bowl in temple for WW
• Use and build acid trip with head places at bottom - collect this
• Good crowd affinity - get jar from crowd
• Put jar and other part in tree
• get gladiator to hit wooden chip
• Bad crowd affinity - get the Shit
• get death of Orion from poison box
• put skull in grinder
• shoot 3 charged Orion shots at grinder - collect this
• plant fertiliser in Odin or Zeus area (one with the red bath area) in cup
• re-pack weapon while waiting to have the fire re-pack ability
• after 2 or so rounds pick it up and put in Danu entrance area by tree
• when fertiliser is smoking green kill a zombie with the re-pack going off
• kill zombies on this spot until your in Danu trial
• Destroy the bulging bits (recommend Hellion Salvo) on each floor
• Go to Ra and press on symbol on pillar
• kill zombies as shown in order
• shoot 4? bull symbols with shield
• go to underground and shoot 4 electric rods (recommend LMG, think gun must be PaP to move it)
• re-pack weapon with electric ability
• go to arena get electric kills in each of 4 electric rod areas
• when all rods are on and buzzing go to challenge podium.
• go to arena challenge podium and interact with a podium symbol for each player
• kill boss zombies with unlimited special weapon

• ur now ready for boss fight, but before that make sure you have:

• Full shield

• Almost full ammo weapons

• Hellion Salvo x5 PaP (my strat)

• Hermunculus (monkey bombs) - not necessary

• 4 perks

• special ability ready to use

• dying wish ready to use

• for boss fight I literally just spammed the elephants with rockets, also one shots the boss zombies. Take off elephants armour and then aim at head or under belly.

Let me know if I missed any steps and I will correct it
