Of course I had to try out the Shadow generations mods after finishing the main game. I will probably play more stage mods in the future if more come out. (and if they not crash when launching)
Egg fleet mod: https://gamebanana.com/mods/562828
Dk mountain mod: https://gamebanana.com/mods/563728
Air fleet mod: https://gamebanana.com/mods/563087
Sky troops mod: https://gamebanana.com/mods/563087
(a lot of sky themed stages)
