Zombies have been a large part of the Call of Duty series over the last few years, and Call of Duty: Black Ops 3 has been no exception. It was just under a year ago that the game received a major piece of zombie-themed DLC called "The Zombie Chronicles," and now fans are getting even more via the game's most recent update.

With Call of Duty: WW2 now released and in need of its own steady drip of content and updates, one would think that Activision and Treyarch would have all but forgotten about a game that's now over two years old. That doesn't seem to be the case, however; not only is Black Ops 3 still receiving updates, but its latest one was fairly substantial considering the game's age and relatively small player base.

The most recent update for Call of Duty: Black Ops 3 introduces two pieces of new content in addition to the usual performance updates. The first is a new game mode called "Infected," wherein one player spawns as the infected and does their best to kill and infect the rest of the players.  Just like in similar game modes in games like Halo, players killed by the infected respawn as new members of the horde. The game ends when either all players are infected or once the survivors run out the clock.

The other piece of content is a new, snow-covered, version of the Redwood map. Just like its less frigid predecessor, Redwood Snow works with all game types.

With a possible Call of Duty: Black Ops 4 listing already out there, it's probable that Call of Duty: Black Ops 3 fans won't be seeing too many more updates like this one. Still, the fact that Activision and Treyarch chose to add anything at all this late in its life-cycle is encouraging. Call of Duty games have gained a reputation for heavily focusing on the casual player base over the last few years.

Since the only people still playing Call of Duty: Black Ops 3 would be hardcore fans of the game, perhaps this is Activision finally doing something to recognize them and alleviate that reputation. On the other hand, this could also be nothing more than a shallow attempt to convince hardcore players that they care about more than just sales. Hopefully, it's the former.
