Infernax

This is my guide for all of the DLC, hopefully the quickest way possible, but if anyone finds ways to shave some steps/time off...please let me know. Achievements will show in italics when I got them.

Run 1
Check Invulnerability and Infinite Jumps are on.
Start a 2 player game, I believe you need 2 controllers.
Once in the game change to both players controlled by 1 controller in the start menu.
Walk left till you see the kill/spare guy, kill him.
Return to the boat, talk to the captain and elect to leave. (Abandoned)

Run 2
Start a 2 player game again, and switch to 1 controller.
Head left to the first save shrine, enter the Game Wizard cheat codes GKZNATEI (99,999 XP) and ALEXKOLE (99,999 Gold - Not sure if you need it but enter anyway).
Pick your Squire and upgrade all his tools (Filth Chisel and All Within My Hands), also upgrade his damage as well as the damage and mana for the main character, to help speed through the game.
Keep heading left until you get to the first village, Darsov, select 2 controllers from the start menu.
On the Squire controller equip the shield and hold to hold it above your head, jump onto the shield with the main character, you may have to walk a bit with the squire. (Blow Your Trumpets Gabriel)
Switch back to 1 controller.
You now need to find an enemy that throws projectiles, I think the earliest place is to kill the Demi-Boss attacking Darsov to the left. Head left, then down when you can and a screen or two to the right until you see projectile throwers.
Switch to the Squire with , press to equip your shield and then to plant it, once they hit it with a projectile. (Unbreakable).
Head back to Darsov and then right and up as soon as you can to get to a town, Katski.
Head right one screen and the first house will be the mayor’s, keep walking up towards him until he stands up, then away until he sits down…repeat until a message of complaint. (One More Rep)
Now head back to Darsov and sleep at the inn, keep sleeping until game over. (Sleep is for the Dead)
*If you have to take a quest from the innkeeper, (the woman by the beds, not the potion guy), then head right until the Skeleton spawns at a grave, kill him, then return to the inn.

Run 3
Main menu, enter the Konami Code (,,,,,,,,,,), select 2 players, again I think you need 2 controllers. (Sweating Bullets)
Once in the game, change to 1 controller. (Remember to occasionally flick the passive controller to prevent having to log both in when it switches off).
Always activate any shrine you see and save, for later!
Go to the first Shrine and upgrade damage, also buy 1 health potion for Joe Carbine. (Deathhammer)
Head left to Darsov and deal with the Demi-Boss, follow the trail of blood left, down, and all the way right until you get to Valeshire Keep.
Inside the keep head right, then up when you can and left until lava, attack the bottom right wall before the lava, (room is directly above start room on the map), eat the chicken. (Meat Sandwich)
Head left one more screen for the key, now head all the was right for the spell (required) and then the boss.
Head back to Darsov, (left, up, right), then head all the way right to the Tohan Passage, then down to Arkos.
Head right, down and right until you get to the shore, use the lightning spell to summon Stormheim Castle.
(Look at the solution to From Vanity to Unity as this has a map). Though I had to head all the way right to get the key, before following the map, then down and left. Open the chest. (From Vanity to Utility)
Head back up and right to kill the boss.
Head back to Arkos and continue left, you’ll reach a 'breakable' wall you can’t break, above the wall is a hut, go in there and buy the teleport spell.
Teleport back to Valeshire Keep. Head right, down, left, down, left, up, all the way left to Combbelton Necropolis in the Cemetery.
Inside, head up then left to get to a key, back up and then all the way right to get another key, back to the second room and head up to get the skill that destroys walls. Head left to take out the boss.
Teleport back to Darsov, head right and up to Katski, right then up and finally right to get to Katska Palace.
Just head all the way right to the boss and kill it. (Don't think you need the skill with Infinite Jumps).
Teleport back to Darsov, head left, then keep heading up and left, and finally down to get to the Kadjanto Stronghold.
Inside head right until you can go down, head all the way left for one key, then back one screen, down and right for the second key.
Head back to the main path and head a couple of screens right, two right, then down and follow this path to the boss. (You don’t need the skill form this castle either).
Teleport back to Valeshire Keep, then head all the way right until you get to Urzon Citadel.
Head inside, keep heading right and finally kill the boss to end the game. (Soldiers of the Wasteland)
