Since the founders left (or, well, was forced out) Infinity Ward, a whole bunch of people decided to leave as well - there's been at least 13 reported cases. And through Twitter and LinkedIn profiles it is now becoming clear that at least six of them have taken up new work at the newly founded Respawn Entertainment (which Infinity Ward co-founders West and Zampella founded after the split with Activision).
The six are programmer Jon Shiring, software engineer Rayme C. Vinson, Todd Alderman, lead animator Mark Grisby, lead environmental artist Chris Cherubini and lead animator John Paul Messerly.
This is probably not the last time people move from Infinity Ward to Respawn either, so we're keeping our eyes open on future developments.
