Call of Duty: Modern Warfare 4's October 23 full release, following campaign early access and DMZ rollout, has driven the 88.5% market-implied odds for Steam's weekly #1 seller through the October 27–November 3 period. The AAA first-person shooter from Infinity Ward achieved immediate chart dominance in its launch week via pre-order volume and day-one sales, outpacing pre-order momentum for Phantom Blade Zero and steady revenue from established titles like Cyberpunk 2077. Trader consensus reflects the typical post-launch sales surge for major Call of Duty entries, tempered by awareness that player counts have trailed some predecessors and that competing releases could still influence final tallies before resolution.
