At a glance
Rugname is the end-encounter reference for Mission 6 of Metal Slug X. 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.
Siberian base and the final betrayal
X’s finale retains the frozen approach, Allen O’Neil, the Rebel base and the Dai-Manji-to-Rugname sequence. Horizontal rockets add pressure on the moving bridge.
The Martians have already appeared earlier in X, so the base’s alien presence follows different foreshadowing from Metal Slug 2. The final battle still turns former Rebel enemies into allies.

Complete your X route
Try this focused practice plan during your run. These are optional goals to set yourself, not extra objectives or achievements awarded by the game.
Recall one X-specific adjustment that helped in each earlier mission.
During the approach, protect a useful weapon by prioritising a safe path.
At Rugname, apply the response that worked in this run rather than assuming the earlier game is identical.
How do I reach Mission 6?
Progress through Mission 5 in Metal Slug X 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?
In a solo session, pause and use Save State after reaching the point you want to revisit. Open the same title in the same browser and use Load State to restore a compatible saved point. Saving again replaces the previous saved point for that title; a link to this guide does not include your save.
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.
The same encounter in another game
This reference name also appears in Metal Slug 2 Mission 6. Metal Slug X revises Metal Slug 2; matching names do not mean that the approach, enemies or experience are identical. SNK’s series history describes the revision.
