Editing Warhammer 40,000 (section)

===Tenth edition (2023)===
''Warhammer 40,000'' 10th Edition was released by Games Workshop in June 2023. Significant alterations were made to the game. Tenth edition revolves around the 4th Tyrannic War, introducing fresh regulations and units for both Space Marines and Tyranids, along with significant modifications to the 41st Millennium's setting. The game has a more straightforward structure, featuring more concise Indexes and a restriction of six stratagems per army. Instead of the current codices, free and downloadable indexes are accessible. The Psychic Phase has been eliminated, with "Battleshock" tests taking the place of the Morale Phase.

Much like Ninth edition, Tenth edition introduced four new box sets: first with "Leviathan", a limited release set that came out at the start of 10th edition.<ref>{{cite web | url=https://www.wargamer.com/warhammer-40k/10th-edition-starter-set-leviathan | title=Full reveal of Warhammer 40k 10th edition starter set Leviathan | date=29 April 2023 }}</ref> Also, three "starter sets" were introduced: the Introductory set, Starter set and Ultimate Starter set.

While Firstborn Marines and Primaris Marines miniatures were sold alongside each other between 2017 and 2023 for the eighth and ninth editions, many Firstborn sets have been discontinued coinciding with the release of the tenth edition. This decision by Games Workshop to retire Firstborn miniatures via [[planned obsolescence]] is controversial, as Primaris Marine units have better in-game abilities than their Firstborn counterparts for a given points cost, and longtime players who have collected large Firstborn armies have complained that they are being forced to purchase Primaris miniatures in order to remain competitive at official Games Workshop tournaments.<ref>{{Cite web |date=2023-07-24 |title=GW continues cull of Warhammer 40k Space Marine kits |url=https://www.wargamer.com/warhammer-40k/space-marines-firstborn-cull |access-date=2024-11-14 |website=Wargamer |language=en-US}}</ref><ref>{{Cite web |last=Harrison |first=Adam |date=2023-07-24 |title=Warhammer 40K: Space Marine Range Is Shrinking Again |url=https://www.belloflostsouls.net/2023/07/warhammer-40k-space-marine-range-is-shrinking-again.html |access-date=2024-11-14 |website=Bell of Lost Souls |language=en}}</ref>
