here's how the animation montage sequence looks with the game programming implemented. this is being run in simulation mode for the movie capture, so the spawned beetles just sort of wander about since the player never spawned. usually, the spawned creatures would go after the player.
the initial animation montage that was created for the badlands boss first attack sequence in flutter bombs. this montage is composed of 2 animations. the turn around with a shell opening is linked to an idle loop running at different speeds, after which the original turn around loop is run again, but in reverse.
