Metal Gear Acid is a turn-based collectable card game. It was the first game in the Metal Gear series for the PSP. A Java ME version for mobile phones was released by Glu Mobile in 2008 titled Metal Gear Acid Mobile.

Acid focuses on turn-based tactics, using a trading card-based system to control the main character's movements and actions. Acid in the name stands for "Active Command Intelligence Duel". The cards are not truly collectable, as the game is complete with a single purchase. However, the game does feature deck design and deck optimization elements. The game allows for multiplayer gameplay by wireless ad-hoc connections of two PSPs.

Before each round, the player can customize the deck of cards used by the main characters. Most cards are based on elements spanning the entire Metal Gear series, such as weaponry, characters, and even the Metal Gear itself. When the game is started, the player's hand can consist of a maximum of six cards. The maximum number of cards in a deck increases with overall progress. In action mode, the player can choose to use the cards as intended or use them to move the character. Most cards only allow the player to move three spaces, while certain cards let the player move up to six or higher.

Cost is an important factor in gameplay and can be summed up as the weight of the player's action. With some exceptions, all cards have a cost attached to them and when used this cost transfers to the player. Cost varies radically from card to card. The higher the cost a character has, the longer that character must wait until their next turn. For example: if a player character has a cost of 15 and a guard has a cost of 10, then the guard's turn would occur before the character's.

Some cards can be equipped; cards such as weapon cards, can have other cards attached to them in order to improve performance. In order to fire the weapon, another weapon card that uses the same kind of ammunition must be equipped. Some weapons don't need to be equipped and can be used by themselves, however, they are discarded afterwards. Other cards that can be equipped include equipment cards and action cards.

Multiplayer, or "Link Battle", is also a new feature. Two PSP systems running Acid can link wirelessly, allowing players to face each other in a "sneak-off". The objective is to collect several diskettes before the rival player. Diskettes can be stolen by another player, so there is an emphasis on avoiding detection.

Battles begin when the player comes into contact with an enemy on the overworld. During a battle, BRS can aim and shoot with her rock cannon at enemies, block against attacks, and sidestep to avoid them completely.

Throughout the game, players can earn abilities that can be equipped to BRS and used in battle, each with their own cooldown periods. These include offensive attacks such as a powerful blast, a sniper rifle, or support abilities that can increase BRS' stats such as her attack or defense.
