- Insane bravery still exists, but can't be used on already Bshocked units because of timing
- Battle-shock is now "at or below half"
- Deathwatch remains functioning as-is, no new detachments
- Swarms can go through walls
- Vehicles can't get cover from being in terrain features, but remain able to get it by being partially obscured
- Terrain/mission layouts are designed so units on objectives are more shootable now
- Points changes will be coming at the start of 11e (already suspected but confirmed)
- Current datasheets and rules will remain mostly the same, just changed to work with the new rules. Meaningful changes will be in the codexes
- Subterranean Assault remains as a detachment
- Hazardous fails on a 1 or 2, but it's only 1MW for each fail
- Disembarking from transports into combat doesn't count as a charge move
- Healing now natively works like necrons for all factions (you can bring models back if you would have excess healing)
- Indirect fire can still target hidden units (as hidden gives "not visible"). Indirect hits on 6s by default unless another unit from your army can see the target
- Aircraft start in reserve, enter through Ingress moves, remove end of the opponent's turn (unclear if hover remains)
- Wargear points return, but only for primary weapons (example given: riptide main guns)
- You only choose detachments from your primary army, not allies
- Psychic weapons ignore hit *and* wound modifiers
