The Mini-Sub 88 is a rebel submarine in Metal Slug 3.


The rapid expansion of the Rebel Army meant that they will soon need a vehicle for each differing environments on the earth. After some designing, Rebel engineers came up with the Mini-Sub 88, created to explore and conquer areas underneath the waves. These tiny submersibles were remotely-operated and A.I. controlled was therefore require less manpower. This means it can be sent to locations that were normally harmful to human beings. Its larger cousin, U25U, is also remotely-operated .
