Help finding a map

[Manjarate?]

Hi, when I was little I remember playing a custom map which, as far as I remember, was like this: you built a base and had to defend yourself against enemies. There were custom models for the soldiers, and you could also upgrade those soldiers from different eras, starting with Vikings (for example) and progressing to modern soldiers (as well as planes and tanks, if I remember correctly). I also remember that you could build walls and things like that. What I'm not entirely sure about is whether the enemies came in waves, but it seems they did.
