Today's Update On The Great Modern Warfare Developer BailoutS

Call of Duty: Modern Warfare 2 developer Infinity Ward continues its slow crumble today with the departure of two more key team members, sources close to the studio tell Kotaku.

Longtime Infinity Ward employees Mark Grigsby and Paul Messerly have both left the studio, the team's lead animator and lead character animator, respectively. Grigsby had been with Infinity Ward from 2005, spending more than five years at the company. Messerly was there from the very beginning, moving from former Medal of Honor developer 2015 Inc. to Infinity Ward in 2002. Both former employees have updated their LinkedIn profiles to confirm that April 2010 marks the end of their tenures at the studio.

Former lead animator Mark Grigsby may be familiar to Call of Duty fans as the inspiration for and voice actor of Staff Sergeant Griggs from Call of Duty 4: Modern Warfare. He's also the guy who ably rapped over the end credits of that game.

The departure of Grigsby and Messerly leaves Infinity Ward at least 13 employees weaker since March 1. That number includes high level staffers like fired studio founders Jason West and Vince Zampella, plus a quickly growing list of team leads and veteran developers.

According to sources close to the studio, morale at Infinity Ward is unsurprisingly low due to a worrying lack of leadership.
