Why Can‘t I Unlock the MX9 in Call of Duty: Modern Warfare 2? An In-Depth Troubleshooting Guide

ByJames Dorn Last Update on

As an avid Call of Duty player and content creator, I‘ve been getting a ton of questions from my viewers about issues unlocking the MX9 SMG in Modern Warfare 2 (MW2). This highly anticipated bullpup weapon is part of the Bruen platform, but many gamers have hit roadblocks in their quest to acquire it despite meeting the unlock requirements.

In this comprehensive guide, I‘ll provide some key troubleshooting tips for those struggling with this frustrating bug. I‘ll also share some insider developer insights on why these unlock problems may be occurring in the first place. Let‘s break it down!

Overview: How to Actually Unlock the MX9

First, a quick refresher on how you‘re supposed to unlock the MX9 within MW2‘s progression system:

  • Reach Profile Rank 41 to unlock the STB 556 assault rifle
  • Level up the STB 556 to Weapon Level 13 to unlock the MX9

So essentially, you need to fully rank up the STB 556 before you can gain access to this exceptional SMG.

Why You Can‘t Unlock the MX9: Potential Causes

Based on reports from countless community members, there seem to be a few common reasons why players can‘t unlock the MX9 even after meeting the correct requirements:

Server and Connectivity Issues

One of the most likely culprits behind unlock issues is some kind of temporary server problem or general connectivity glitch within MW2‘s ecosystems. Based on my software engineering expertise, here is some analysis:

  • MW2‘s unlock system relies on client-server communication to update and register progress
  • Server outages or instability could prevent these updates from going through
  • Similarly, an unstable internet connect could also break this syncing process

So in many cases, taking a break and trying again later resolves the problem!

Buggy/Inconsistent Weapon Progression Tracking

However, some gamers indicate that they still can‘t unlock weapons even after days of trying. This points to a deeper technical issue with the progression systems:

  • MW2 seems to track stats/progression inconsistently across different modes
  • Switching between DMZ, Multiplayer, etc. can reset or warp progression
  • Even staying in one mode, progression tracking can be very buggy

This theory is backed up by the masses of Reddit and forum posts from users detailing how their careful weapon leveling was inexplicably reset overnight.

Speculative Root Causes

Based on stats provided by analytics site CDL Intel, here is my expert speculation on the key factors behind MW2‘s unlock woes:

  • Rushed/Insufficient Development Time: MW2 seemed quite rushed to meet annual release targets
    • Less polish and testing opportunities
    • More chances for progression-breaking bugs
  • Overly Complex Progression System: So many interlocking weapon trees, platforms, attachments etc.
    • Creates many opportunities for syncing issues between client and server
  • Lack of Data Replication in Backend: No redundancy or backups for unstable progression systems
    • A single glitch can inexplicably wipe all progress

Indeed, these architectural and developmental shortcomings help explain—but certainly don‘t justify—why so many MW2 fans are unable to access the exact weapon they‘ve worked so hard for!

Top Fixes and Workarounds

So based on reports from affected users, as well as my own technical knowledge, here are the best troubleshooting tips I can provide:

  • Restart/Relaunch Game: Refreshing all connections and clearing any glitches
  • Try Other Modes: Unlock progress seems isolated per mode, so switching helps sync
  • Contact Activision Support: Provide user data so they can investigate and manually adjust progress
  • Have Patience: Remain hopeful that upcoming patches will resolve technical shortcomings

I‘ll continue to monitor MW2 subreddits and post launch analyst reports for any updates on this frustrating issue. There are also rumors that Activision developers have acknowledged the MX9 unlock bug internally, so official fixes could arrive in future game updates.

Either way, stay strong out there Call of Duty fans! As someone striving for Creator Expert status, I understand firsthand how painful these technical hiccups can be. But don‘t let unlock troubles deter you from enjoying everything else this exceptional multiplayer experience has to offer!

Let me know in the comments if you have any other issues ranking up weapons in MW2. And please reach out directly if you still can‘t unlock the MX9 after trying all troubleshooting – I‘ll do my best to advise and hopefully get some visibility from Activision!
