MAX: Mechanized Assault and Exploration

M.A.X.: Mechanized Assault & Exploration is a turn-based strategy game released for DOS in 1996. The objective of the game is to colonize various alien planets by building eco-spheres for your colonists to live in and defending them against enemies. No Crack needed. Use the patches though...
Might want to get dosBox, this way the game will be more stable.
This was the original RTS game, but unfortunately it has a bug that will cause the game to run out of memory around Turn 120~. Maybe it'll get fixed one day... Try the mod MAXR if you want multiplayer
Initial seed wil be slow, sorry. (Hopefully people seed after they leech...)
