Warhammer 40,000 (Ninth Edition) is a board game released in 2020 for 2–6 players, 120–240 minutes per game, and ages 12 and up. Its main mechanics are Variable Player Powers, Scenario / Mission / Campaign Game, and Measurement Movement.
The 9th edition rulebook is full of changes and clarifications but essentially these new rules are, at their core, less ambiguous than the prior edition and do a good job at removing multiple interpretations. It also introduces a new Coherency rule and checks and Command Phase. The New Coherency Rule - The 6” vertical limit has been reduced to 5” in the new edition (the height of a single floor of Sector Imperialis/Mechanicus buildings) and if a unit has 6 or more models then each model needs to be within 2” of 2 models now. Engagement Range codifies the concept of “within 1″ of the enemy” into a single term for reuse across the rules, and also adds a new feature – in 9th edition it now has a vertical component (5″) allowing for fights across different elevations in ruins, over crates or around barrels. Measuring distances now has a section of the rules all to itself. Unit strength and Destroyed units rules have been updated. The Command Phase is brand new for 9th and consolidates a few different things into one phase of the game. Essentially everything that happened in the void between the start of a turn and the movement phase, the “before the movement phase” rules. --from the publisher’s website
