I love Reckoning's easter egg, it feels the most classic of the bunch. Most of the steps make logical sense, yet they were made much harder to discover than other BO6 maps, the mop bucket in particular. There's quite a few interchangeable steps, so you can create your own flow that makes optimization fun to do while juggling all the good side easter eggs like the shooting gallery, free perks and aether blade, just to name a few. Then we get to the third tower, and is that not the coolest sequence pre-bossfight in the game? It felt reminiscent of the God of War 2018 sequence going up to the Mountain's peak iykyk. And to then top it off with two different bossfights is the icing on the cake, tho I generally go against Richtofen for the challenge as S.A.M. just drags a bit too long
