Mother Computer Z is the final boss in Nemesis GB. As its name states, it is the cental computer of the Bacterian fleet in this game.
Mother Computer Z, unlike the Brain in Gradius, doesn't go down without a fight!
Like most other Gun Walls, this final enemy fires a lot of bullets and generates enemies from top and bottom.
There is one rather odd, easy way to defeat this boss - pretty much as soon as it appears.
If the player has a shield equipped, ramming the boss will instantly defeat it.
