Call of Duty Mobile reveals World Championship ruleset

Call of Duty Mobile has unveiled the final ruleset that will be used at the Call of Duty Mobile World Championship 2025 taking place from November 7th to 9th.

Ahead of the event, Activision has made several adjustments to the regulations that will be implemented at the season-ending tournament.

Within the final changelog ahead of the World Championship, Activision has added a range of weapon-specific attachments to the ruleset to increase their viability for competitive play.

The 3-Line Rifle, Machine Pistol, Oden, RAM7, SKS, Tundra, Type 63 and USS-9 all feature new attachments that could spark a shift in the competitive meta during the mobile shooter title’s biggest tournament of the year.

In addition, the Engineer and Overclock Perks have been added to the Perk Restriction list, preventing players from selecting them when building a loadout ahead of a match.

Activision stated that the October 14th changelog is the final update to Call of Duty Mobile’s competitive ruleset of the year. The publisher also revealed that ‘all participating pros at the World Championship Finals will be polled and surveyed,’ enabling the publisher to gather feedback ahead of the 2026 season.

For 2025, the Call of Duty Mobile World Championship heads to Katowice, Poland, a city that’s no stranger to high-profile FPS esports events.

In total, 16 teams from across the world will compete across a GSL group stage and a double-elimination bracket playoffs to determine the eventual champion. The best team will walk away with the lion’s share of its $850,000 (~£640,067) prize pool.

Following victory at the Call of Duty Mobile Major 2025, Chinese team Wolves Esports heads into the tournament as one of the favourites. The competition will also feature defending World Champions Team Elevate, which also won the CODM World Championship 2025 Garena Finals in August.
