Are you ready to test your bases? See if your fortress will hold up to sustained and prolonged attack? (And perhaps more than a little hyperbole.) The minecraft invasion mod is a mod that adds hyper dangerous mobs with all new abilities to the game. Mobs that can build bridges over your lava moat and tunnel up under your feet. Mobs that emerge out of a tar pit and become flaming zombie torches of doom if exposed to open flame.
