At a glance
Sea Satan is the end-encounter reference for Mission 5 of Metal Slug 4. It is followed by Mission 6.
Mission numbers refer to the original campaign order. Boss names follow the community mission reference; they are encounter identifiers, not official stage titles.
Cargo ship boarding
Mission 5 boards a cargo ship defended by pirates and Rebels. The vehicle selection includes the Forklift and Metal Claw. Sea Satan is the closing encounter, with Brave Guerrier also providing support during the battle.
The final threat is not confined to Sea Satan alone. Continue checking the surrounding action when concentrating fire on the main target.

How do I reach Mission 5?
Progress through Mission 4 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 5 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.
