Mars 2.2 map suitable for 5 to 6 players.
In Mars, you and 5 other people (computers won't work) build up your defences and attack forces in order to claim the barren land of the Red Plant. I forgot to mention that those 5 other people are competing against each other as well, because this is an FFA. You play as a race of humans and mechs, the latter of which will be available later on as you progress in the tech tree.
The buildings are a custom mix of buildings from the real game but contain special upgrades and units for the custom race on Mars. Some of the buildings contain mana for healing and stat altering purposes which can be handy if your base is getting attacked. There is also a heroes' building for, you guessed it, heroes when you get enough resources gathered.
Watch out for the creeps that are scattered along Mars' surface because you'll need a good sized attack force in order to take them all out without taking sufficient damage. It is fairly easy to avoid them unless you are crossing the canyon in the middle.
