The game developers have stated that void crusades won't be changed or added, so I'm not expecting any major issues with the paths getting outdated.

The last round of updates to my void crusade guides was done with the game at patch version 2.3.4, during the Season of Warp Surge.

This guide was last updated in April 2021. I added a bit more general Void Crusade information, and added the Relic farming part.

What changed:

• I changed my steam name, to bring it in line with reddit, the game and discord.
  
• The season objective with all Info Fragments got changed to 75 minutes (was 60 in the Season of Inferno)
  
• A Versioning/Update history section was added
  
• An Info section was added
  
• All guides got (roughly) the same format
  
• Amber got an Info Fragment path, and a discussion of its merits
  
• Viridian got a Relic farming route

• Bonus, Secret and Covert missions add a higher bonus to loot than regular missions
  
• Starting with the Season of Warp Surge, item levels will go up to 100. You need to do missions of at least +7 difficulty to get level 100 items, if you are 100. I have yet to find out - all other things being equal - whether an extra Tarot card, or extra difficulty would lead to more level 100 items
  
• I'm pretty certain the Servoskull can not spawn right next to the starting node on the VC map, but it can spawn one node away. Apart from that, it seems random. And you can get unlucky, and it will shop in a high difficulty mission, in a room full of Elites
  
• In almost all cases, the Servoskull is exactly in the direction you were facing/moving when you got the notification

• You will NOT get the info Fragment if you pick it up, and then concede the mission
  
• The mission timer starts when the missions starts (not when you launch it)
  
• The mission timer stops when you fulfill the mission objective (not when you leave the mission)
  What that means for you: Do mission objectives first, until you get the 'Quit' popup. Then go hunt for cogitators and Info Fragments

• If you die AFTER the mission objective has been fulfilled, the crusade continues
  
• Abandoning a mission ends the hardcore crusade
  
• Failing a mission (that includes hot pursuit and vip/guard rescue) ends the hardcore crusade Rescue missions get very dicey around +6, depending a little on Tarot Cards and enemy type

• Two keys are granted for finishing the Supreme Mission
  
• A key is granted after completing five missions of any kind
  
• A key is granted after completing at least two Bonus missions
  
• A key is granted after completing all Covert and Hidden missions
  
• A key is granted after defeating the Wandering Servoskull

• Dataslate Decryption Terminals don't have a map icon. Use Vrakos' guides if you get stuck
  
• Cogitators for secret missions don't have a map icon. However, they are always in a 'secret' room you have to teleport to
  
• 'Survivors' are in a group of guards, and one of them has a label of 'Survivor' when you hover over him
  
• Hot Pursuit: Keep your mouse over the fugitive, and hold down the magic new button you have (usually '5')

• I always make my paths with the difficulties peaking in the middle, and then working down from there. It has been pointed out to me that that's not fully optimal, because some missions give bonuses for subsequent missions after completion, like '10% extra damage vs. Rebels'.
  My take on that is: If you are really, really struggling to finish the missions, the bonuses might actually help you a bit.
  At the same time, if you are really, really struggling with some normal missions on Void Crusades, my advice would be to hop onto Discord and to ask for help.
  And, my focus when doing Void Crusades is gaining loot from the Supreme Mission. The quantity of Relics goes up with difficulty, and we will also get more level 90+ items. So I'm bumping up the difficulty there, and by the time we are at the Supreme Mission, we will have also collected all the bonuses.
  
• As of this patch, the highest possible difficulty you can run a mission at is +29, and it's on the Crimson Void Crusade
  
• For regular (and Supreme) missions, the difficulty gets set when the mission is made accessible
  
• For Secret and Covert missions, the difficulty gets set, then the difficulty modifier is added for subsequent unlocks

Mission number. Difficulty level of the mission. Difficulty increase.

• 1: 0
  
• 2: 0
  
• 3: 0 +1
  
• 4: +1 Mech map. Crazy loot.
  
• 5: +1 +1 Cogitator here to unlock mission 6. Screenshot at the end of this section
  
• 6: +1 Info Fragment here. Defend the Stormwatcher mission with cogitator for mission 7. Screenshot at the end of this section.
  
• 7: +2
  
• 8: +2 Mech map. Pretty good loot as well.
  
• 9: +2 +1
  
• 10:+2 +1
  
• 11:+2 +2 Info Fragment here
  
• 12:+1 +1 Info Fragment here. Cogitator here to unlock mission 15
  
• 13: 0 +1
  
• everything is unlocked, any order from here
  
• 14:+7
  
• 15:+6 drops here are pretty bad (especially without tarot cards), I would just run through and destroy the three targets
  
• 16:+4 Info Fragment here
  
• 17:+4
  
• 18:+3
  
• 19:+3
  
• 20:+3
  
• 21:+2
  
• 22: 0 Info Fragment here. Lower right of the map, on the way to the third target.
  
• 23:+6 Final Mission

Mission 5 Cogitator (teleporter inside VIP room)
Mission 6 Stormwatcher event

This path unlocks the final mission pretty early.
The hardest mission is possibly 15, a mech map with heavy penalty.
The final mission is pretty easy, as nothing on the map one-shots you.
If you are struggling with the earlier mech maps already, it's possible to do 11 after 12 and 13. This will have the mech map at +4, BUT it will bring the final mission to +8.
Or you just run through it and destroy the targets for the mission objective.

Map 14 has two Fire Prisms at +7. If those are harder for your build than +7 mechs, you can switch 12 and 13 and get map 14 at +6 and 15 at +7.

Map 4 might actually be the fastest way to earn cash in the game, if you have enough Ecru void shards to run repeat crusades.

Added bonus: This path comes with a safety device: If you fail/abandon mission 11, you can STILL do exactly what you intended to do by going to mission 12 from the left hand side

There might be a different crusade with an even shorter path. I started with Ecru and loved what I found.

• 1: 0
  
• 2: 0+1 Info Shard. If you go straight between the two targets on the right hand side of the map, you cant miss it
  
• 3:+1
  
• 4:+1+1 Covert cogitator. Not really important here.
  
• 5:+2
  
• 6:+2+2 Info Shard. Pretty close to the left hand mission target.
  
• 7:+4 This is a mech map, so be careful with Tarot Cards.
  
• 8:+4+2
  
• 9: 0+1
  
• 10:+6
  
• 11:+7 Mech map. Crazy loot here. Be careful with Tarot cards, I got +90% damage for all monsters and that hurt quite a bit. If you are particularly unlucky, you can just do the sabotage and be done with it to progress.
  
• 12:+7+1 Nothing too bad, not a single villain or elite monster
  
• 13:+6+2
  
• 14:+8 Cogitator here to unlock mission 15
  
• 15:+10 Just rush through, destroy the three targets
  
• 16:+10 Again, just rush through. Destroy the warpgates, evade the villains/bosses, teleport out.
  
• 17:+10 Final Mission. Boss is some extra beefy Space Marine. That never did any damage to me.
  The sorcerer villain in the same room was worse.
  edit: If you use tarot cards on map 11, you WILL fill up a completely empty inventory, all three tabs.
