This mod is absolutely amazing. I played it years ago and it was so fun. I looked forward to it everyday and it still brings back amazing memories.
Today. Yes there might not be a lot of players on... but I bought a server exclusively for me and my friends, and it is still the best mod co op game (possibly game alone) i have ever played it.
Good job guys.
Has over 1,000 downloadable maps to play! Also has a AoM server ran by Cocyx, which is great. I love this mod. I would run it and create my own listen server on a loaded christmas map to keep me in the holiday mood
