User blog:Spartian300/alternative history: Middle ages invaded.

Okay, i know i am new and all, but i have an idea for a map game: an alien invasion in the Middle ages. However, it will have the aliens attacking earth through a portal from their planet. They are in their own middle ages. I will try to make it, but i will gladly allow you all to join. the time peroid is the 1500, so try to get guns first! ill be the invaders, okay?
