Horus Heresy Review: Legion Mastodon Heavy Assault Transport

Goooooooood afternoon,

Today I'm going to delve into one of the newer offerings from forge world for the Legiones Astartes, the giant delivery truck of death that is the Mastodon Heavy Assault Transport. This is a delivery truck of death in both the sense that its occupants are likely to be a bundle of death but also the vehicle itself has serious offensive capabilities. And for the princely base price of 700 points you would bloody hope so!

Unit Stats

Ok so the Mastodon comes with the following profile:

BS  Front   Side   Rear   HP
 4      14        14      14    10

This is, in and of itself, impressive! Especially as it is a super-heavy transport so it cannot be one shot exploded by a lucky gunner. It needs to have all of those HP's ground down to zero. It has no fire points, but it can carry up to 40 regular models, though as part of this complement it can also carry up to 2 contemptor dreadnoughts with each counting as 10 models for the purpose of carrying capacity.

Additionally the Mastodon has two access points which are at the front and the rear of the vehicle.

Overview - even before you delve into the equipment and special rules of the Mastodon it has a fearsome presence on the table and this only improves the more you look at it.

Special Rules

The Mastodon, as one might expect, has a plethora of special rules to compliment its hulking exterior. These are Assault Vehicle, Enhanced Defensive Fire, Reinforced Shell and Void Shields (2).

Assault Vehicle - lets start with the simple one first, this vehicle is obviously designed to deliver a deadly payload and there wouldn't be much point to the bloody thing if you had to stand around scratching your arse (or ass for our West Atlantic cousins) for a turn!

Void Shields (2) - That is right! This AV14, 10HP monstrosity also has TWO AV12 void shields. Collapsed by glancing, penetrating and D hits, these can be returned on a roll of a 5+ at the end of each of your turns. Dear Throne this thing is surviviable.

Enhanced Defensive Fire - As long as one unit still occupies the Mastodon it can use its sponsons to fire overwatch, thus removing the negative of having zero fire ports. This overwatch is fired at BS2 for the standard weapons, whereas template weapons inflict D3+1 automatic hits. So its overwatch fire is better than normal! The most effective way to deal with this machine, close combat, just became a less friendly prospect... These can fire only once but at separate units as long as the unit is in their arc of fire.

Reinforced Shell - A lovely rule in a game where often bigger and badder is better. The armoured shell of the Mastodon is so secure that it contain and blast that occurs. Therefore you apply a -2 modifier to the catastrophic damage table when rolling for the Mastodon's destruction. Should a 0 or -1 occur then the Mastodon remains in play but functions as a ruined building, with both doors acting as free access points. Very fluffy and cool.


As you would expect this beast is loaded with weapons and other equipment, lets just start with the standard equipped offensive battery shall we:

Two Sponson Mounted Lascannons - The standard lascannon that can fire overwatch (only its arc of fire) at BS2.

Two Sponson Mounted Heavy Flamers - Standard Heavy flamers with D3+1 overwatch

One Fixed Forward Siege Melta Array - 12", S9, AP1, Heavy 4, Small Blast, Melta, Stone Burner

Stone Burner - if this weapon inflicts a penetrating hit against a fortification or building then it instead causes D3 penetrating hits.

One Turret-mounted Skyreaper Battery - 48", S7, AP4, Heavy 5, Twin-linked, Skyfire, Interceptor

OK so the Mastodon has pretty much everything covered here! Flamers for hordes, lascannons for armour, skyfire and interceptor for flyers and then magma death cannon for anything stupid enough to sit within 12 inches in front of its face! Blimey oh riley!

In addition to its offensive arsenal the Mastodon also has a searchlight, smoke launchers AND armoured ceramite to boot. So you not only have 10 AV14 hull points nestled behind two AV12 void shield, but it also isn't vulnerable to ranged melta!!


Optional extras with this beast include the following: 4 hunter killer missiles, an upgrade to be a super heavy command vehicle, an upgrade to have command vox relay.

Command Vox Relay - While the Mastodon is in play this allows you to add or subtract 1 to your reserve rolls. In addition any deep striking enemy units that suffer a mishap will have -1 applied to the deep strike mishap table as long as the Mastodon is in play.

Super Heavy Command Vehicle - As far as I am aware this allows re-roll of morale within 24 inches. Any one care to correct me if that is wrong?


This will be a short section as this is a pretty self explanatory! You pack it full of death and drive it at the heart of the enemy. There is no room for being timid with this UNLESS you are facing something packing  shit tonne of destroyer weaponry. D weapons are pretty much the only serious threat to this other than a Primarch in close combat with retinue. But you shouldn't be letting yourself get charged really, but dictating the charges. 

I would recommend the command vox relay if you have any reserve support coming in like flyers, but otherwise give it a miss. In terms of the command vehicle, that could be very very useful in 30k given that Astartes are not fearless, but again that really depends on what you have put inside of it!

So much of how you use this depends on the rest of your force that I will leave that up to you :)

Peace out,



  1. Erm, how much do you get for a kidney these days?

    1. Wait.. I thought this was why you became a father? First born children always go for a mint Nick ;)

  2. Sweet jeebus that thing is nasty, pretty sure it will have a huge cost from FW as wella s the 700 points.

    1. I imagine the price will be in excess of the Ordinatus Macro engine, so around £350-400...

  3. So, basically, it's a whole Land Raider Spearhead Formation crammed into one Model. Nice.

    I don't see myself ever getting one of these, because I wouldn't use it very often, but it would be really fun to load it full of Blood Claws and Ragnar Blackmane and just go paint the town red.

  4. A beast! Definitely going to add one to my Death Guard!

  5. Can you transport a leviathan dreadnought with it? Because if so, my economic future looks grim ;)

    1. Just says dreadnought so yes. Same as the new stormbird; 5 Leviathans and orbital strikes every turn.

    2. It actually specifies Legion and Contemptor Dreadnoughts. As far as I thought the Leviathan was a separate entity compared to the regular (legion) and older (contemptor) classes.

  6. As a thing to note, the command vox relay replaces the skyfire array. Means your more vunrable to flyers but better able to bring in your own, so you're potentially killing the enemy's flyers with yours.

    Nice review and in the words of WW40K Australia; go up the guts!

    1. Ah yes, I forgot to put that bit! I will edit later :)

  7. Nice - I struggle to find a good reason to include one in my Thousand Sons, but it is almost an auto-include in an Iron Warriors or Imperial Fists army in my opinion, being the big siege legions. It's a beast!

    1. I absolutely love this model, but never will I buy it. Just doesn't fit my play style, but I would love to face one across the table!

  8. God my iron hands just started crying tears of joy

  9. Interesting - Looks like you could kitbash a perfectly acceptable one from a rhino and land raider kit, some plasticard, and maybe a few turret weapons from puppetswar or similar. Verrry interesting.
