This is exactly what it sounds like: Clockwork Knights and Megacrafts all mashed up into one mod. It's very handy if you have a Mac- both mods load happily when mashed together. I played around with it for a few hours and didn't see any issues. Nothing has been changed in either mod (and permission was granted by both parties to post this). Enjoy! P.S. - Thank you Ruigi and zaratustra for making these excellent mods!
