The game saves your progress as you play. Hence when you start a new game, there is no choice but to play level 1. However, if you for example, completed levels 1 through 3 but died on level 4, the game saves until level 4. The next time you select "Arcade Mission", you will be presented with a screen with a mini-map of where the game's levels occur up to and including the last level played. The only way to gain access to all six levels of the game when you start "Arcade mission" is to have completed the game beforehand under any difficulty setting.
Hint: Survival mode:
Successfully complete the game under any difficulty setting. Select "
", go to the "Attack" option after
enlisting in the army, and the survival mode option will be unlocked just
beneath pin point mode. To access survival mode, just highlight that option and
press A. In survival mode, you only have one life and the game measures (in
meters and kilometers) how far you get before you are killed by enemy gunfire.
In this mode, you have unlimited ammunition, and there is no point scoring
system. Combat School
Hint: Exiting a Metal Slug tank:
To get out of a Metal Slug tank at any time on any level, press Down + B.
Hint: Level 6: Hidden Metal Slug tank:
There is a hidden Metal Slug tank in level 6. All other levels have the Metal Slug tank in plain view. Play through the level until you arrive at the place where Morden blows up the bridge from his helicopter. Then, drop down to the boat with the machine-gun turret. Allow the boat to proceed to the first pillar with the barrel marked "DANGER". Do not shoot the barrel. The tank is hidden in the top right-hand corner of the screen. It is obscured from view by the railings of the highway and it does not have the "IN" pointer on top of it. To get to the tank, throw a grenade at the pillar to clear it of enemy soldiers. As soon as they die, jump from the boat and onto the pillar. Once on the pillar, jump twice to reach the top of the barrel. Jump once more to get onto the highway itself. Then, just jump into the tank and drive backwards to fall back down onto the boat. You can now blast through the first pillar to proceed.
