As the countdown continues to September 23 launch of the fourth and final Black Ops 4 Zombies map, Treyarch has continued to showcase new teaser images across social channels getting fans ready for the launch.

New teasers dropped on September 16, including a new profile image from Treyarch and an image asset on Twitter.

Here’s the Twitter profile picture, which translated is “Ascension.”

In a tweet posted, they shared an image of a weapon diagram in Call of Duty: Black Ops 4 with the caption, “When you can’t take the heat, it’s time to improvise…”
