Treyarch have posted a development update regarding Call of Duty: Black Ops 4's Zombies mode, writing that the team added a new technology to help them track some more complex and esoteric types of crashes, especially in Easter Egg quests.
The team stressed that stability is an absolute priority for Call of Duty: Black Ops 4 and its modes and will remain to be until all the Zombies issues are erradicated. With that in mind, Treyarch apparently added a new tech to allow them the track crashes and "isolate the issues with the highest frequency".
The company reminded that the list of fixes is being worked on in priority order, so some niggles are likely to be higher in the pecking order than others. Treyarch wrote that Call of Duty: Black Ops 4 Zombies players can expect several fixes in the next few updates, which to be fair are quite frequent.
Nevertheless, Treyarch also warned that the complexity of Zombies Easter Eggs presents a "unique set of challenges in reproducing, fixing, and thoroughly testing the fixes before release". This means that the issues take longer to fix as well, so they called for fan patience throughout the process.
Treyarch reiterated their intention to be delivering a steady stream of updates, so as to keep Call of Duty: Black Ops 4 fans fully in the loop. They also reminded that they're doing everything in their power to make Black Ops 4 "the best and most-supported game that [they]'ve ever made".
Even though the company did their best to tweak it to a useable and non-op state, Call of Duty: Black Ops 4's latest update removed the 9 Bang grenade from Blackout, much to the satisfaction of the masses. It's likely that it will make a comeback at a later date, as Treyarch have decided to tweak it to a non-infuriating state behind the scenes, so you may want to stay tuned.
Of course, with the news of Call of Duty: Black Ops 4 raking in 550 million in just three days, many are wondering why Activision and Treyarch simply don't invest in servers, but that's a discussion for another time.
