How to Play a Game of Legions Imperialis

As you may have

heard on Sunday,

Warhammer: The Horus Heresy – Legions Imperialis will be up for pre-order

this weekend

. To make sure that you’re up to speed when it’s time to send your armies forth, we’ve prepared a quick primer and video on how a regular game is played.

Mustering an Army

Before you do anything, you’ll need to summon some troops to march under your banner. This starts with picking an Allegiance – either Loyalist or Traitor – then choosing which faction you’ll use as your Primary Army List. At present, you may either pick Legiones Astartes or Solar Auxilia, but you can take allies.

Individual armies are made up of Detachments, which function like units in other games – squadrons of tanks, entire platoons of infantry, or singular massive war machines. These are organised into Formations, which provide your army list with a strong thematic core when you’re picking Detachments. Each army must have at least one Formation for every 1,500 points in its total cost.

The Orders Phase

Unlike other Warhammer games you may have played, Legions Imperialis has players constantly swapping control during a turn, rather than taking them one after another. This keeps the action dynamic, despite time spent on strategic planning, and forces players to adapt quickly to unexpected moves from their opponent.

Every Detachment must be given an Order, which is issued in secret during the Orders phase. Each player places tokens face-down next to their Detachments, which are then flipped over simultaneously once everyone’s done.

Orders allow Detachments to do anything from standing in place and shooting – which gives them an advantage over anything choosing to move and shoot – to marching and charging into close combat. Not only will players have to try and predict what their opponent might do, but they must also ensure their plans will work regardless of who claims the Initiative.

The Initiative Phase

Legions Imperialis is a game of alternating activations, where players take turns to move or fight with individual Detachments in each phase. So even though you won’t need to watch your army weather an entire turn’s worth of firepower before responding in kind, it’s still important which of your Detachments you activate first, as battles can hinge on a key unit being utilised at the right time.

Seizing the Initiative is no more trying than winning a roll-off with your opponent, but whoever wins can choose who goes first. If you’d rather wait for the enemy to come to you, or just want to play some crazy mind games, try letting them make the first move.

The Movement Phase

Starting with the one who holds the Initiative, players activate one of their Detachments and move it according to the Order they were given. Advancing units are able to move and fire while Charging units trade the ability to shoot for extra speed and the opportunity to get into close combat with their foe.

Detachments may also March, doubling their movement (or tripling it if they’re dismounted Infantry). Charging units can also lock opponents in close combat before they enact their own Orders, making Initiative vital in close engagements where fights are often quick and bloody.* 

The Combat Phase

Ranged and melee combat both take place in the Combat phase, where action alternates between each player. Crucially, Detachments which took the First Fire Order give up their chance to move in return for shooting before any other units fight – which is as powerful an advantage as it sounds.

These Detachments resolve their attacks one by one – once again via alternating actions – followed by all Combats – melee encounters in which opposing Detachments have come into base-to-base contact. Finally, any Detachments given an Advance Order can unload their guns at the enemy. Morale checks are taken during the Combat phase once an attack has finished resolving. Failure will change that unit’s Order to Fall Back, forcing them to back away from combat. Should a Formation take casualties equal to or exceeding half its original strength, it will also become Broken, and any remaining Detachments will find it much harder to fight effectively.

The End Phase

During the End phase, any units with a Fall Back Order will attempt to flee via their own battlefield edge. Fleeing units may take further damage if they’re forced to move through enemy Detachments during their escape, and failing subsequent Morale checks will keep them running headlong for safety/making a disciplined and tactical withdrawal.** Importantly, fleeing units cannot be issued Orders in the next round.

Finally, Victory Points are scored in missions that use them, according to a range of parameters. Once everything is resolved, a new round begins.

This primer only gives a very surface-level look at the structure of a turn in Legions Imperialis. There’s loads of tactical depth – Flyers on strafing runs, massed teleport assaults, overwatch fire, and many other actions. We’ve got more from Legions Imperialis coming this week as we approach the pre-order launch this Saturday.

* In most cases, units don’t get an armour save in close combat, so even powerful elite Detachments can be brought down if left unsupported.

** It all depends on which side you’re viewing it from!
