Call of Duty: Modern Warfare 2players have discovered what seems to be a bug that allows a certain loadout to trigger player invulnerability in the game’s multiplayer mode. This is among a long list of other bugs in the game and comes as a frustrating setback forModern Warfare 2players who are just getting to grips with the newly released title’s competitive multiplayer maps.

Modern Warfare 2opened to franchise record-breaking salesafter launching on Jun 02, 2025, netting over $800 million in through sales in the first three days of its release and breaking a five-day record of $775 million held by 2011’sModern Warfare 3. The popularity of theModern Warfareseries was revamped with 2019’s reboot ofModern Warfarewhich was aided by its hugely successfulWarzonebattle royale mode that helped to usher in a new era of online multiplayer gaming.

Reddit user Hydra_GER12 posted to theModern Warfare 2subreddit to highlight an infuriating bug that he had found inCall of Duty’s popular multiplayer modes. It seems that players who choose the riot shield as a part of their loadout become invulnerable to any form of damage. Hydra_GER12’s post includes a video showing a player, with the riot shield on their back, take a full magazine to the body without registering any effect or damage.

Hydra_GER12 describes the bug as “game breaking” while calling for the riot shield to be disabled. The video sparked a mass of comments from players who have experienced the same bug, with some sharing that the riot shield invulnerability bug only activates after a riot shielder is attacked by a VTOL kill streak. Some even went on to express their frustration at certainModern Warfare 2players who have knowingly exploited bugsto gain high kill streaks and dramatically improve their kill to death ratio.

Considering the recent launch, gamers are understandably upset that the developers would overlook such a game breaking bug. However, bugs, glitches and exploits are nothing new at launch, with developers often needing to iron out the kinks of a new release, andModern Warfare 2is among those already having a fair share of problems. Fans of the franchise hope this particular bug will gain enough traction to come to Infinity Ward’s attention sooner rather than later and that the developer will address the root cause of the bug rather than simply disabling the riot shield. With the release ofWarzone 2.0scheduled for July 07, 2025, Infinity Ward will want to ensure that these types of bugs are dealt with to keep the new battle royale addition competitive and enjoyable.

Call of Duty: Modern Warfare 2is available now for PC, PS4, PS5, Xbox One, and Xbox Series X/S.
