Out of the games within the Warzone Trilogy (the 3 games that came out and were a part of warzone) Black Ops Cold War is easily the best. The campaign is really fun and has some good twists as well that at are both possible and impossible. Multiplayer is probably the most fun I've had in any cod in a while. I love the idea of the strike maps (basically ground war maps but only a reasonable chunk to make them more engaging) and the fact that since it's release, there has been a Nuketown 24/7 playlist. Finally zombies, I've said this to all the people I know who ask about zombies, if you are looking for OG zombies, bo3 on pc, however if you are looking for zombies that is just fun, engaging, and easy to get into, then this iteration is the way to go. The fact that your first match of zombies is where you are at your weakest and as you play more you can upgrade the various tools you use throughout the match (perks, field upgrades, weapon skills, and even the ammo mods) is still really satisfying, especially since they are permanent. Not to mention Both MP and Zombies have amazing mastery camos. Yeah I'd suggest this without a doubt, even more than whatever crap IW is putting out.
