This text is absent in Metal Slug 2, as the standard Game Over screen will be shown before the player is taken to the ranking screen. Prior to Metal Slug 3 (and only in the original Metal Slug and Metal Slug X), completing the game will also display the same Game Over screen as explained above, but with an additional text saying 'PEACE FOREVER!' on the bottom of the screen. The screen consists of the words 'GAME OVER' drawn on the ground next to tank treads and alongside a military helmet on the top right. When the player fails to continue after 10 seconds, they are led to the original Game Over screen. In some games, the player is given an option to continue or return to the main menu, while in some games, the words 'Mission Failed' appears instead.

The Game Over screen also appears after the credits screen in some games of the series. If the player has failed to continue after the timer has passed out, the screen will fade into the color of blood red along with 'Game Over' written on their Status screen then which leads to the actual Game Over screen. Whenever the player loses all of his/her three lives, he/she is given an option to continue within 10 seconds (20 in Metal Slug 6) as long as they have any credits left. 2.7 Metal Slug Defense and Metal Slug Attack.2.5 Metal Slug: 1st Mission and Metal Slug: 2nd Mission.
