Call of Duty: Modern Warfare developer Infinity Ward is a little bit smaller today, as one more longtime employee has left the embattled studio, officially a trend. Veteran programmer Jon Shiring has parted ways with the home of Modern Warfare.

Shiring announced his resignation from the Encino-based Infinity Ward via Twitter, as spotted by 1UP, saying "After almost 6 years at Infinity Ward, I resigned today. I'm incredibly proud of everything we accomplished and I'm going to miss everyone." He follows fired co-founders Jason West and Vince Zampella—now leading Respawn Entertainment, and recently departed lead designer Todd Alderman and lead software engineer Francesco Gigliotti.

Shiring worked at Infinity Ward for five years, 11 months, according to his LinkedIn profile, departing the same day that Zampella and West announced their new studio backed by Electronic Arts, Call of Duty publisher Activision's chief rival.

That makes Infinity Ward at least five longtime employees shorter as of March 1. And the bleeding of key talent at the Modern Warfare developer may not stop there, as we've been told another development lead on the team has also quit the studio. We're still attempting to verify that claim and will update when we hear more.
