Call of Duty: WWII is finally out, and along with a new story-driven campaign, the game brings back the series' Zombies experience in the form of Nazi Zombies. This time, however, developer Sledgehammer has made some changes to the popular game mode.

Not only does Call of Duty: WWII's Zombies mode feature a more in-depth class system and abilities, it also gives you more apparent objectives to complete. While the mode doesn't feature any objective markers, you can pull up a small to-do list by pressing touchpad, which will highlight nearby points of interest for you.
