Enjoy! In what is my big swan song as far as video content for CTR:NF goes, I revisited the adventure mode, but rather than do a normal 100% playthrough, I decided on one with many additions, alterations, and of course cheat codes. Now cheat codes are not allowed when playing adventure mode, so all the races and such were done outside of it and edited in place of the normal stuff you'd expect to see in the mode. It's fun to see everything added to the game all come together in one giant package at the expense of the video being very long.

Timestamps for this long video.
