Codex_ Alpha Legion

Codex: Alpha Legion

*Author’s Note: This is an unofficial rule set for use in games of Warhammer 40k - 8th edition. These rules are not
compatible with those in Codex Chaos Space Marines. All the special rules, strategems, and datasheets needed to
play this army are detailed here.

Army Wide Special Rules

Deep Cover Operatives

Any Alpha Legion Character unit may secretly deploy within another friendly non-character infantry unit.
Secretly assign each Character deploying this way during deployment limiting one character unit per
infantry unit. At the end of any phase you may reveal any number of Alpha Legion Characters. Deploy
them within 1 inch of their assigned units. If a unit hiding a character is destroyed immediately place the
character on the board near as possible to the destroyed unit. Models in Deep Cover do not take up
any slots towards the capacity limit of transports.

Asymmetric Organization

Alpha Legion armies do not use any Force Organization Charts. Instead the army may be comprised of
any combination of units with the only limits being those specified in each datasheet (and the “Rule of
3”). The army is always counted as battle-forged and generates the baseline 3 command points as
such. The army may generate additional command points by taking Command Assets as described in
the list below:

● Insurgency Uprising - 5cp: 3 Units of Insurgents. Each unit must begin the game at least 20
strong.

● Goliath Convoy - 4cp: 2 Goliath Trucks and 2 Units of 10 Insurgents.
● Inhibition Force - 2cp: 2 Units of Seekers and 1 Hydra Librarian.
● Insurgency Outriders - 1cp: 1 Unit of Jackals and 1 Unit of Ridgerunners.
● Assassination Force - 1cp: 1 Hydra Assassin and 1 Unit of Headhunters.
● Twinborn Task Force - 2cp: 3 Units of Twinborn Operatives.
● Command Coordination - 4cp - 1 Information Advantage Coordinator and 2 Tactical Support

Squads.

Any single Command Asset only generates CP the first time its conditions are met.

Warlord Trait

I am Alpharius: All Alpha Legion Astartes Characters are your Warlord. Slay the Warlord is only
achieved if there are no Alpha Legion Character units on the battlefield upon the end of the game.
Additionally, once per game at the end of any phase you may select two Alpha Legion Astartes
Characters and swap their positions.

if there are no Alpha Legion Character units on the battlefield upon the end of the game. Additionally,
once per game at the end of any phase you may select an Alpha Legion character and replace it with a
Chaos Lord.

Special Issue Wargear

One of the following items can be equipped to the appropriate unit after the mission is chosen but
before deployment begins.

Precision Orbital Strike Indicator (Harrowmaster and Informational Advantage Coordinator Only): At the
start of the first battle round place a marker anywhere on the board more than 6 inches from your
opponents deployment zone. As long as an Alpha Legion Character is still alive you may call in an
orbital strike at the end of any phase. Select a weapon profile below and select an enemy unit within 6"
of the target marker. You may not target characters with a wound characteristic of less than 10. Use
this ability once per game.

● Cluster Bombs: Heavy 4D3, S4, AP -1, Damage 1, This weapon automatically hits it's target.
When allocating wounds from this weapon your opponent must select the model closest to the
target marker.

● Earthshaker Bombardment: Heavy 2D3, S6, AP -3, Damage 2, This weapon automatically hits
it's target. When allocating wounds from this weapon your opponent must select the model
closest to the target marker.

● Laser Destroyer: Heavy D3, S9, AP -4, Damage 3, This weapon automatically hits it's target.
When allocating wounds from this weapon your opponent must select the model closest to the
target marker.

Disorientation Grenade (Seekers, Tactical Support Squad, Hydra Assassin Only): At the end of any
phase a unit armed with a Disorientation Grenade may target an enemy unit within 6”. Roll 3D6. If the
total is greater than the enemies LD value then the enemy unit may not hold objectives for the
remainder of the battle round. One use only.

Dimensional Key (Hydra Librarian Only): The bearer may re-roll one or both dice for a single psychic
test per turn and knows the Incursion power from the Malefic Discipline. Friendly Insurgency units who
begin the morale phase within 12” of a Daemon unit must take a morale test adding 2 to the result.
