Following a successful beta of Call of Duty: Black Ops 4 Blackout, Treyarch thanked all participants and explained that armour, audio and inventory are the main takeaways from testing, each of which will be adjusted ahead of launch.
At the moment, Treyarch are wary of making any radical cuts in how armour works, which is why they mostly focused on limiting its accessibility. They did tweak level 3 armour back when they added Fast Collapse mode, but that was to address its near-invincibility.
As part of the changes made over the course of Blackout's beta, level 3 armour's spawn frequency has been decreased by 75 per cent and it lets through more damage to the wearer. Treyarch did say they're aware of concerns of level 3 armour being too powerful, so Call of Duty: Black Ops 4's battle royale mode may still be getting some nerf time.
The dev heard the complaints about overly loud teammate footsteps and their occasional lack of directional clarity, some of which will be fixed by dialling them down, the rest by the awareness perk. Treyarch said that directional issues will be addressed by launch as well, announcing various audio presets for headphones or surround sound users.
PlayStation 4 users should expect Call of Duty: Black Ops 4 to come with improved inventory and item management, since most have complained about slow item pickups. Treyarch seem to have taken to the PS4 community's idea of enabling an option in settings to allow fo tapping a button for instant pickup, although there's still some testing to be done.
Treyarch also shared some stats gathered during Call of Duty: Black Ops 4 Blackout's beta and we've learned that players have slain 7.5 million zombies and killed 123 with a basketball. Also, the longest kill with a combat axe was 213 meters / 698 feet - wrap your head around that.
