This review is based on the Campaign that I have just completed on BO6 before I move to the multi-player. I found the campaign thoroughly entertaining over 4 days. It starts off slow, then as the story progresses it becomes really enjoyable. There are a nice range of missions to complete: Firefights with elites and using a range of weapons at your disposal, some timed missions, some puzzle missions, some vehicles missions, even a quick game of poker. A nice mixture of challenges to overcome. I also liked the zombie missions, there was something satisfying about gunning down a load of zombies. I really enjoyed the key card mission with the range of bosses and zombies. There are other challenges such as lock picking, radio listening and hacking, that weren't that hard, but still enjoyable. Well, with the storyline, it was great imagination, but it just wouldn't happen, me taking on a whole base in Russia instead of stealth, but it makes for an amazing game. The graphics are good and the gameplay, you can tell this is a triple A game, it was awesome. Just about the right length of campaign, took me about 15 hours. I really recommend this game, especially on Game Pass. Looking forward now to the multi-player. You always need a campaign in a game to learn a lot of the mechanics. Also, great public relations by sending me an e-mail saying congratulations for completing the campaign. Some of the reviews have been negative due to performance issues. For me on PC, I have a specific gaming laptop, it did take about a minute to load to the title screen, then when I went to campaign it rebooted the game to change modes. But when in the game, I had hardly any glitches, the very odd time it slowed down when there was a lot going on fast in the game. Well done the developers, I had lot of enjoyment with BO6.
