Hint:
Prisoner cards: Every time you rescue ten prisoners, you will get a card.
Hint:
Solider cards: You will get soldier cards when you kill 100, 200, 300, and 999
soldiers (for a total of four cards).
Hint:
Type R card: There is a card in the beginning of mission 4 called Type R. If
you equip the card, your Metal Slug turns yellow and the gun moves in
reverse. For example, if you are moving forward your gun will point in the
opposite direction.
Hint:
Collecting card and kills: Even though you have an unlimited amount of lives, all of the
things done before that will not count after you die; try not to die while
fighting the Boss.
Unlock All cards card:
Collect all 99 cards in the game to get the final 100th "All
cards" card.
Unlock Decoration Card:
You need the "paper thin" card. Turn it on, then complete any
mission. With paper thin turned on you will die with just one hit. The
easiest way to get the decoration card is to complete mission 2, mainly
because there is a Metal Slug at the near start of the level which is
shielded, so if you can manage to get through the level with the Metal Slug
it shouldn't be as difficult to get the card.
Unlock mission cards:
You just have to clear the mission, you can die as many times as it takes:
Parachute route in mission 5:
In mission 5, jump into the plane slug. Now as soon as you start the level
proper, press L to crash the slug. You will eject and go onto a different
route where you parachute down into the enemy docks.
