Hostage Rescue is the thirteenth mission in Metal Slug: 2nd Mission. Only Gimlet has access to this stage. Eight prisoners exist in this mission.
After Gimlet traversed through the hidden tunnel inside of a waterfall, he finds a gulag. Margaret recalls Col. Delta being MIA and assumes he is being held there. Margaret orders Gimlet to break in and rescue Col. Delta, much to Gimlet's chagrin due to running out of ammo in his previous mission.
In this mission, Gimlet is only allowed to use his knife and whatever pineapple grenades he can find. Col. Delta is represented as a blue-colored POW and is held at the upper-rightmost room of the gulag. Rescuing Col. Delta ends the mission.
|Found hidden tunnel in transit. I found something like a gulag.|
|Secret Gulag info received. It’s there, eh? The MIA Col. Delta… is probably being held there. Break in and save him.|
|Too bad, but I’m out of ammo! Can’t proceed!|
|Improvise! Over and out!|
Completing this mission proceeds to Mission 13 (Intelligence).
