How many weapons are in MW4?
Beta roster: 22. The documented MW4 Open Beta contains 22 accessible weapons across nine classes. Launch arsenal announced: 33. Activision has announced a broader 33-weapon launch arsenal, but Launch identities not yet fully documented here. This page therefore answers Beta weapon-list searches with the 22 verified records and clearly separates announced launch scope from evidence we can publish today.
Each record links to a readable weapon page with class, access status, evidence label and available specifications. Identity and unlock fields describe what appeared in the Beta; dated balance records can change when a patch updates damage, range, multipliers or handling, while the original screenshots remain historical evidence.
The final major documented Beta weapon-tuning pass arrived on August 31. Infinity Ward published its Beta wrap-up and launch priorities on September 1. The M4 base-gun profile remains effective August 28, while the M4 Hurricane attachment and Krait P68 profiles are the latest documented August 31 records. Use the MW4 Patch Notes to separate dated values from older captures.
