Infinity Ward has lost a further two veteran staffers following Jason West and Vincent Zampella's controversial dismissal by Activision just over one month ago.
The resignations of programmer Jon Shiring and designer Mackey McCandlish come a week after software engineer Francesco Gigliotti and lead designer Todd Alderman walked. Shiring had spent six years at Infinity Ward, Gigliotti seven, and Alderman and McCandlish eight.
Whether the quartet will find a new home at West's and Zampella's new studio Respawn Entertainment - announced yesterday - remains to be seen.
But Activision isn't phased, and claims there's still "a deep bench of proven talent" at Infinity Ward ready to work on "exciting new projects", according to Gamasutra.
The publisher added that the formation of Respawn complete with publishing deal with EA was "no surprise".
"This agreement comes as no surprise to Activision given the myriad of improper activities detailed in the cross-complaint filed on Friday against Jason West and Vince Zampella," it said.
Jason West and Vincent Zampella are names synonymous with headlines in recent weeks. Eurogamer sat down with them yesterday for a chat.
