About & sources
A squad-made MW4 guide for players at every level. Short answers, easy to read on your phone between matches.
How we check things
We look for at least two independent sources, published since the October 2026 launch, for every unlock level, build and Apex detail. When they disagree, or only one source has a fact so far, the page shows a yellow note saying what's uncertain so you know what to double-check in game. We leave a number out rather than guess it. The meta moves with every patch, so every page carries the date it was last checked.
Last checked: Oct 26, 2026 (Launch · pre-Season 1).
Where the data comes from
- Official Call of Duty guides and patch notes.
- Community stat trackers that publish pick rates, fire rates and time-to-kill.
- Guide sites with progression tables and launch builds.
Fire rates and time-to-kill are measured by players, not published by the developer, so treat them as close rather than exact.
