The GT/Invitational construction rules have been posted for a while, but they in short are:
  1. You may not select more than 2 total Detachments, and must contain a Primary detachment
  2. You may not select more than 1 Combined Arms Detachment
  3. If you do select a Combined Arms Detachment, is must be your Primary detachment
  4. All Formations, Codices, and Dataslates published by 8/1/2014 are considered legal
  5. Forgeworld rules will not be legal for 2014, though are likely in some capacity for 2015
  6. You may select 0-1 Fortifications from the following:
    1. Aegis Defense Line
    2. Imperial Bastion
    3. Skyshield Landing Platform
    4. Firestorm Redoubt
    5. Vengeance Weapons Battery
  7. Conjured units are not considered part of an explicit Detachment. As a result, benefits from your Warlord such as Conqueror of Cities and benefits granted by being a part of a given detachment do not apply to Conjured Units. Furthermore, as a RAW clarification, Conjured Models interact with other models as per the Allies Matrix, regardless of the Faction that summoned them.
  8. You may not use Lords of War or Forgeworld Rules. Expect these to be reassessed for 2015.
  9. Allied detachments may be selected from the same Faction as your Primary Detachment
The Narrative construction rules are:
  1. Your list must follow the Battle-Forged rules from the 40K Rulebook and Codices for a 2,000 Point Army. All official GW Dataslates and Formations will be allowed during the Narrative and will be used as written by GW.  Stronghold Assault and Escalation are also allowed in accordance with 7th Edition.
  2. Forgeworld/Imperial Armor rules and units are LEGAL, but Apocalypse-only formations are ILLEGAL.
  3. Lords of War are LEGAL.  
  4. However, Fortifications, Gargantuan Creatures, and Super-Heavy Vehicles using a Hellstorm template or blast larger than 5” may not reduce cover to less than a 5+ when resolving wounds against a model that is not a Gargantuan Creature or Super-Heavy Vehicle.

The Trios construction rules for the Singles / 2000 Point Variant are:
  1. Unbound or Battle-Forged, no restrictions (Forgeworld/etc. allowed)
