(Copy of my BO6 Review)
At this point, I've beaten the campaign, achieved the first multiplayer prestige and finished the main quest in one of the two zombie maps.

I can comfortably say that this is the best Call of Duty has been, as a full package since probably the original Black Ops.

The campaign is easily the best of the series. Zombies sees a return to form of wave-based survival, which was sorely missed after the disappointing attempt at an open-world experience in MW3.

The loadout system in PVP-multiplayer has been greatly overhauled, and gunplay is slower overall but feels much better.

My only real gripe with Black Ops 6 is the map selection in multiplayer, which currently contains way too many small-size maps, that don't allow for full exploration of the new loadout-toys, but s far this has not been enough to ruin the experience for me, though I hope to see larger maps being released as part of the post-launch content.

Definitely worth your time, if you have any interest in the COD franchise.
