Ok this is a diffrent kind of map in freebuild and all around its a map were you try and get YOURSELF KILLED!!! You keep on sending huge invasions all over and its really hard to kill yourself unless you cheat and spread out your X-man. No map designing was involved well I guess the castle but its pretty plain.
If you dont know how to get an Invasion in a freebuild press F1 in game and click invasion an whoulla you can choice what enemys you want.
It took me around 22 game years to kill myself ha ha ha.
