Just finished Call of Duty: Black Ops 3
Great group of guys in the VFX department.
Treyarch is really ambitious with what they want to give players. They try their hardest to make the best experience. The other teams I cant speak for.
I put in my few weeks notice and will be going with a group I used to be with. Good stock/pay/hours, however it wont be very mainstream since its mobile stuff.
