Editing Warhammer 40,000 7th edition (section)

=== General stuff ===
*The rulebook was written by [[Jervis Johnson]], [[Robin Cruddace]], and Simon Grant.
*The Core Rulebook's split into three parts: One for the collectible (modeling and painting) part of the hobby, one for the fluff, and one that's just the rules. All together, they cost $85. ($140 in Australia)
**Some time after 7E and [[The End Times]] went into full swing, GW snapped back into ''their'' logic and re-released the rulebook as a hardcover for double the price of one of those three books.
*Rules from Escalation and Stronghold Assault are included in the new rulebook. Obviously they've left out the data sheets so that you still kinda sorta need to buy those books if you wanna use their content properly. 
*Introduction of [[Tzeentch|Maelstrom of War]], an alternative to the standard set of Eternal War missions. A set of missions (6, to be specific) which revolve around special "Tactical Objectives". Those objectives are drawn from one of 36 cards and award Victory Points for completing them. Example Tactical Objectives that have been mentioned include "manifest a psychic power", "destroy a flyer", and "kill a Character". Tactical Objectives can be exchanged for another one in the deck at will, and if one is completed it will be replaced with a new one. The new 7th edition codices all seem to be adding additional Tactical Objectives which can only be used by that codex's faction.
*Considering that the Tau, Space Marines, and Eldar have gotten rewrites, it's likely that GW is planning to update every faction to work within 7E parameters, a ballsy choice considering they also annihilated Fantasy and forcibly launched Age of Sigmar.
*You can ignore the Force Org chart if you wish, resulting in an "Unbound" army list.  However, using the FOC to make a "Battle-Forged" army list which grant you a variety of benefits. The traditional FOC is now referred to as a "Combined Arms Detachment" which allows you to reroll Warlord Traits and lets your Troops control objectives even if an enemy scoring unit is within range of them (unless they also happen to have Objective Secured). Other FOCs are starting to come as new codices are released.
**The potential for abuse with Unbound lists is obvious- as long as the units themselves are legal, the allies chart is followed, and the point limit is adhered to, literally anything goes. Like an army made up of nothing but HUNDREDS of cheap troops models (like Grots/Cultists etc) for the [[tarpit]] to end all tarpits, or an army consisting entirely of superheavy vehicles. But on the bright side, it also allows you to field fluffy armies legally (e.g. the First Company of a Space Marine Chapter, the [[Phoenix Lord]]s, or a regiment of the Death Korps of Krieg).
**Even worse is a trend that began with the Necron Codex: Decurions, or Detachments made entirely of formations, some with absurdly unbalancing rules.  Considering that they're not going to be updating any of the forces before into getting some, this leads some armies (Tyranids, Sisters of Battle, and Orks in particular) with a very big shafting.
*Kill-Team remains out of the book, though the rules Games Workshop has are still valid.
*They're redoing the Allies matrix. See pic related. And now you can have Grey Knights ally with Daemons, allied with Tyranids, allied with Tau. Granted, this army's going to be pretty much a bunch of paperweights most of the time with Come The Apocalypse rules.
** Battle Brothers: Benefit from warlord traits and reserve rolls, ICs can join friendly units, can repair each other's vehicles, and can embark on each other's transports. Allied troops with a battleforged list get objective secured as well.
**Allies of Convenience: Act as enemy units that can't be charged, shot, attacked or targeted, can't move within 1" of each other, and are impacted by stuff that affects enemy models.
**Desperate Allies: As AoC, but with One Eye Open.  
**Come the Apocalypse: Ally like Desperate Allies, but must deploy at least 12" apart.
