The Mars Mechas are the walking quadropods in Metal Slug 3
These giant contraptions are defense drones used inside the Rugname. They attack by dropping bouncing bubbles from their bellies similar to an oversized Drop Shot. When defeated, the body disconnects from the legs and crashes into the ground, crushing anyone underneath it.
