Call of Duty: Black Ops 4 has dropped its latest update, and it’s a meaty one, weighing in at over 9GB. The most exciting bullet point is the addition of Nuketown, which is PS4 exclusive for one week. You can check out a trailer for the latest version of the fan-favorite battleground, below.

In addition to Nuketown, the new update speeds up Black Market progression by adding Daily Tier Skips, patches up some of the problems plaguing Zombies mode, and rebalances the game’s MP Specialists (Alex, in particular, has received a nerf).
