Warhammer 40,000 (Tenth Edition) is a board game released in 2023 for 2–6 players, 60–240 minutes per game, and ages 12 and up. Its main mechanics are Variable Player Powers, Scenario / Mission / Campaign Game, and Measurement Movement.
For Warhammer 40,000 (Tenth Edition), every single element of the game has been revised and rewritten from the ground up for an entirely new, and more cohesive, experience. Plenty of rules remain the same – but all rules have been reassessed and, if necessary, rewritten to work perfectly. Datasheet Cards for your faction now contain all the information you need to play the game at your fingertips. All the rules for your army are now contained exclusively on a single double-page spread, there are also far fewer Stratagems, relics, and special rules to keep track of. Universal special rules are back in the game – It doesn’t matter if you’re making a Dimensional Translocation or preparing Death From Below, it’s all a Deep Strike now! Core Stratagems are also much more reactive in the 10th edition. This means there’s less waiting around during your opponent’s turn and plenty more opportunities to attack and defend, even while your opponent is making their moves. Combat Patrol is the new mode for Warhammer 40,000. It pits the contents of one Combat Patrol box against another and it’s a fantastic way to begin playing. Objective Control is a measure of how good a unit is at holding a contested objective, replacing Objective Control. The confusing days of Objective Secured are gone. —description from the publisher
