At a glance
Amadeus Mother Computer is the end-encounter reference for Mission 6 of Metal Slug 4. This is the last of this title’s 6 main missions.
Mission numbers refer to the original campaign order. Boss names follow the community mission reference; they are encounter identifiers, not official stage titles.
Mainframe infiltration and escape
The finale descends by rope into a communications base, passes reactor and robot-production areas, and includes a robotic Allen encounter before the Amadeus Mother Computer.
Destroying the computer is followed by a timed escape corridor. Keep playing after the mainframe battle instead of treating its defeat as the point to close the session.

Close the run deliberately
Try this focused practice plan during your run. These are optional goals to set yourself, not extra objectives or achievements awarded by the game.
Keep the session open; this title does not currently offer Save State or Load State.
Separate the goal of completing the campaign from the goal of improving its medal bonuses.
At the final encounter, concentrate on readable inputs and a safe next position.
How do I reach Mission 6?
Progress through Mission 5 in Metal Slug 4 to reach this mission. A new arcade run begins at Mission 1.
The Play button selects this title in the collection. It does not launch this specific mission, change the original game’s difficulty or unlock later stages. Use the guides below to read ahead while your campaign follows its normal order.
Can I return to Mission 6 later?
Metal Slug 4 does not currently offer Save State or Load State because restored graphics can be unreliable. Keep the current page open and use pause for a break. Closing or reloading ends that run; a guide link cannot restore it.
Manual continues include free credits. Automatic continues can be changed in Options & Controls → Gameplay. Neither option is a mission selector. Read the save and continue guide.
Controls for this run
These are Classic keyboard defaults; saved bindings take precedence. Touch uses movement plus A / FIRE, B / JUMP and C / BOMB. Arrange touch controls before a long session, or see all controls.
