Multiplayer: Sledgehammer Games with this title decided to just copy the engine used for MW2019 and tweaked it to be more fast paced and have more vibrant colors. Which wasn't really a bad move, although the map pool still not being that great and the implementation of breakable walls was a step back from being as good as Cold War. The TTK was fine but the outrageous headshot multiplier was not something to be desired.

Ranked Play: Treyarch's implementation of Ranked was something which made the game more enjoyable than it originally was at launch, since the Public match experience was not that great. Although the Mode should have been added earlier in the life cycle of the game. And it lacked Demotion protection and SR Loss protection when a player disconnected during match.

Multiplayer: Treyarch never fails to impress even with the short time Activision gave them to develop this title. Good maps, smooth movement, and high TTK make this CoD title a significant improvement from MW2019.

Zombies: As someone who used to dedicate my time on CoD Zombies a fair bit when I was younger, Cold War's approach to the mode was to make it a little more catered to the casuals. I always liked the challenge with the Mode when there was a limit to how many lifelines you could have to stay alive, however with Cold War they were so many so-called innovations and features that were added that resulted in more possible lifelines and overpowering yourself and your weapons. Such things were the ability to customize the starting weapon (including attachments), leveling up the perks which at some point makes them overpowered, the rarity system where the damage of the gun could get improved significantly during the game and etc.

Other then being more casual than earlier titles the Mode was still enjoyable. One thing I did like with the new implementations was it did make it so you could have multiple purposes for playing every game session. Other then doing the Easter Eggs (which mostly was mid) there were upgrading guns, upgrading perks and unlocking camos (which was zombies exclusive).

Map pool was small and underwhelming, and it doesn't help that half of them weren't that good with Treyarch's standards of map design. However I personally enjoyed the launch map Die Maschine and Mauer Der Toten which came out after the disappointing map Firebase Z. Outbreak was a cool concept of multiple bigger maps in one with the removal of the traditional round counter. I did like how it allowed you to be more free to do whatever on each map, that being doing side missions and/or main missions. However the execution could have been better, at some point it would get repetitive with the same handful amount of mission types just cycling through and the population of zombies on the maps not being up-to-par.

Multiplayer: Compared to Infinity Ward's predecessor which atleast had good movement and gunplay. Infinity Ward decided to take a step backward with releasing a game with even worse maps (Santa Seña being the perfect example) and worse movement. The gunfighting is also something that has been worsened by the lowering of TTK which makes Infinity Ward's philosophy of catering to the casuals even more catastrophic for the aspect of competitiveness.

Ranked Play: There is atleast a shed of light in the darkness surrounding this game with Treyarch's development of Ranked. Treyarch's mission of developing a Ranked play system in every CoD title is the only thing that makes Infinity Ward's titles somewhat enjoyable. They introduced Demotion protection and a improved SR system. Doing their best to make a non-competitive game more competitive. However the lack of good maps, movement which could use some improvement in speed and low TTK makes Treyarch's mission hard.
