Guide for Warhammer 40,000: Mechanicus (2024)

In the Caestus Metalican, you will be shown 6 Magos on the left side of the screen. These senior Tech-Priests give you your missions and will appear with a yellow exclamation mark by their image when they have a mission for you. There is also a hidden 7th Magos at the top of the screen that is shown with . Missions are unlocked by discovering new sections of the tomb and by completing previous missions for each Magos. It is not exactly clear how different sections of the tomb unlock but it appears running up the Awakening Meter and completing missions for Scaevola and Videx unlock them the fastest. As mentioned previously, you have a limited amount of time to complete the game so it is possible that you won't have enough time to complete every mission in the game. At the bottom of this page, I have included a short list telling you what to prioritise on your playthroughs. Each mission will give a difficulty selection which isn't always right. I suggest not tackling normal difficulty missions until you have at least 3 Tech-Priests and not tackling hard until you have at least 4 Tech-Priests who have a fully unlocked Discipline tree. Once you have selected your mission, you will be given a view of the tomb from the Noosphere.

The Tomb

Your first time looking at the tomb from the Noosphere will look incredibly underwhelming but this section of gameplay can ruin a mission before you've even encountered an enemy. The tomb is filled with 5 room types filled with hazards and rewards. These appear random at first but guides can be found below. Prioritise the following rewards: COGs, healing (if needed), reducing enemy initiative, Blackstone. Entering a room that you've not explored yet will cost 2 bars of the Mission Awakening Meter, whilst exploring a room you've already been in won't cost you anything. Plan your path to your objective rooms carefully to use up the least amount of Awakening possible. Sometimes it is better to double back on yourself and go through already explored rooms.

Empty rooms have no indicator on them. They hold no challenge or reward.

Glyph rooms are indicated by a bright green glyph. The Glyphs pose a hidden challenge; 2-3 symbols will appear before you and they either harm your efforts or reward you. At first they might seem random but actually, each Glypth gives the same outcome in every game. A guide to them can be found below. You do not have to choose a Glypth or look at them at all when you enter their rooms. In some situations, all symbols may be a reward or harm. Because there is sometimes no reward, I prefer Events to Glyphs which are more often beneficial. Since explored rooms can be re-entered later, consider leaving a healing Glyph and then returning to it after combat if possible.

Event rooms are indicated by a light blue exclamation mark. These events are forced multiple choices which carry risks and rewards. Unfortunately the outcomes are often cryptic and the most sensible option is actually a trap. Each mission has events tied to them so by following the guide below under each Magos, I have given the solution with the best outcome for each event you will run into. Note that not all outcomes have a positive outcome or often all rewards also come with a cost. Look through the event list before exploring rooms in the tomb and if there's rooms like this, make a save so if you uncover one by mistake you can reload and take a different route. Read the event description carefully as they are often very similar. They will appear as I have given examples below, note that bold events cannot be avoided and rewards underlined are undesirable but unavoidable in some rooms:

Combat rooms are indicated by red Necron units inside them. You are forced into combat upon entering where the objective will always be eliminate all enemies. These are usually low levelled enemies in a small map and pose little threat if dealt with appropriately. Upon defeating them your Mission Awakening Meter will go down 4 bars. This, as well as of the Blackstone you'll get for more downed foes, can make these rooms very profitable later in the game when you can wipe these out in 1-2 turns without taking any damage. However, early game you run the risk of taking extra damage and increasing your meter so avoid them until you feel comfortable to take them on.

Objective rooms are indicated by a yellow exclamation mark. You must enter each one of these to complete the mission. Most of the time these will end in combat but occasionally they will end in an event instead. Objective rooms are tougher than combat rooms, featuring different objectives and harder enemies. Some missions have 1 objective room whereas some have 2 or 3 so don't go all out straight away, save your unit's health and CP for later.

For both Glyph and Event rooms:
- If the reward is increased initiative, but you already have that, instead the Mission Awakening Meter will increase by 2. Avoid.
- If the reward is increased CP but your CP is full, instead you will be awarded Blackstone. Useful.
- If the harm is decreased CP but your CP is empty, instead the Mission Awakening Meter will increase by 2. Avoid.
- If the harm is decreased initiative but you already have that, instead the Mission Awakening Meter will increase by 2. Avoid.
- If the reward is a new item but there are no possible items to unlock right now, nothing will happen.

Tutorial

There is a tutorial which you have the option to skip. Play it in your first playthrough for an introduction to gameplay and an achievement (even if you fail the tutorial, you still earn this). In subsequent playthroughs, skip this as the final objective room of the tutorial is quite hard. All event choices will give the same reward.

Scaevola

Scaevola is tech-obsessed and will happily sacrifice anyone to unlock more technology. They have 12 missions which you will need to complete to unlock an achievement at the end of a playthrough. These missions are a mixed bag and mission 8 is where they start getting hard so don't progress too far here until you're happy with your team.

Videx

Videx is religiously obsessed and would rather purge the Necrons than learn from them. They have 12 missions also which will need completing to unlock an achievement at the end of a playthrough. If all 12 of Videx and Scaevola's missions have been completed on a single playthrough, you will only get an achievement for the last mission you completed. Videx's missions also get more difficult after mission 8.

Khepra

Khepra leads the Skitarii and most of their missions involve supporting your cannon fodder because their heart is too soft. They have 11 missions and each one has a high reward for your team. Missions 1, 4, 7 and 11 will award you with an extra Tech-Priest needed for your 2 achievements. Regardless of the achievement, complete all of Khepra's missions as soon as you safely can as these rewards make the game considerably easier.

Rho

Rho is in charge of maintaining the ship and your supplies. Their missions don't tie in to the story in any major way, nor do they grant achievements, however they do tend to always grant good mission rewards. Complete if you have extra time at the end or if you need a bit more Blackstone and kit to take on your next big mission.

Captrix

Captrix has an obsession with hunting and as a result will reveal the location of all the Necron lords. Each Necron lord is a boss fight which can only be unlocked when 3 other missions in their area have been completed. For instance, to unlock the first boss, Lord Astronomer Ekropis, you must have completed 3 missions in the Ekropis Sector. Each boss fight is tough and should probably be avoided when you first unlock them for a few more missions. They will only have 1 objective room in the dungeon but before reaching the objective room, you will have to travel through every single event and glyph room which will run up the Awakening Meter and possibly weaken your team. Make sure to use this time to gain as much CP as possible before going into the fight so you can end it as quickly as possible. When you enter the objective room, you will be in a unique room and the boss will have unique abilities putting your skills to the test. Whilst you can stay and fight the Necron units that spawn, it is usually best to rush the boss and kill them as quick as possible as the mission will end once they are dead regardless of other Necrons left alive. For every boss you defeat you will unlock an achievement, and you will make the final mission easier as Captrix's final mission is the last mission of the game where you fight the final boss. Every boss that you have failed to defeat before the final mission will appear now so make sure they're all dead. It's also worth mentioning that there is a useful Canticle for defeating 5 bosses (though another boss can be found below).

Xerxetes

Xerxetes is quartermaster of the lesser Tech-Priests that are onboard your ship and he's heard whispers of an uprising amongst your ranks. His missions are vastly different as instead of entering a tomb and working through glyphs and events, you will be fighting a single combat encounter onboard the Caestus Metalican. When choosing a mission, you will be given multiple choice questions, similar to events, which determine what your mission objective will be, where your spawn positions are and what other bonuses you might receive going into combat. The other big difference here is that for the first time ever you will be facing against other Tech-Priests and Skitarii. These missions are all listed as Easy but don't believe that for a second as the Skitarii bear new skills and several Tech-Priests are untargetable at the start of the game. You're going to take more damage in these missions so make sure your team are close together for support and healing. There is no Awakening timer so take your time and scan all terminals rather than destroying them. Completing these missions rewards no achievements but they usually have good item and Skitarii rewards.

Tiresus

Tiresus is your hidden Tech-Priest, revealed with , who is studying Necron texts. His missions tend to follow the same pattern of getting your team to escape, followed by kill all enemies, so consider killing all enemies straight away. It's also worth noting that Tiresus's missions all tend to have a large number of terminals in so by destroying them all, these are great opportunities to run some missions at 0% Awakening. His final mission is a boss fight who is a massive push over but will award you the best Canticle in the game. Finishing this final mission will award you an achievement.
