At a glance
Shoe & Karn is the end-encounter reference for Mission 4 of Metal Slug 1. It is followed by Mission 5.
Mission numbers refer to the original campaign order. Boss names follow the community mission reference; they are encounter identifiers, not official stage titles.
Canyon defences at Ridge 256
The fourth mission moves into a defended canyon. Fixed turrets and Bull Chan vehicles join Rebel infantry on the approach, and an SV-001 is available. The mission ends with Shoe and Karn rather than a single named opponent.
The mix of stationary defences and moving vehicles is the distinguishing feature of the approach. Keep checking the whole screen when attention shifts from one target to the other.

Try this focused practice plan during your run. These are optional goals to set yourself, not extra objectives or achievements awarded by the game.
Shift your attention between your character and the edges of the playfield.
When several threats appear, choose a safe movement first and a firing target second.
At Shoe and Karn, avoid letting one target distract you from the rest of the screen.
How do I reach Mission 4?
Progress through Mission 3 in Metal Slug 1 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 4 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.
