The special tasks in different campaigns in "Call of Duty: Black Ops 6" are different, and the animator is one of them. If you want to do this task, you only need to complete the time trial in the separation anxiety task in one go. , after the first battle to defend the safe house, Woods will talk to Jane.
How to do the battle animator task
Animator-Dark OPS
Complete the time trial in a separation anxiety mission in one go
After the first battle to defend the safe house, Woods will talk to Jane and you will be transported back to her memory. You'll be kicked off a cliff and into an abyss (like falling off a trailer). You will then be prompted to run over a hand and a timer will start. You need to complete it before the timer runs out. If you fail, restart the checkpoint before dying/failing and you should be fine.
My best advice is to start before the timer starts when sprinting off the jump. You need to jump over the barrel room, crouch, and crawl under the barrel at the end. You don't have to pick up a weapon, just pick up the grappling hook on the island later. Then, ignoring all enemies, quietly walk to the door. For me, I have 6 seconds left, so this should be easy to do. The card becomes active once you enter the office.
