Because Snake suffers from severe amnesia right from the beginning of the game, the events after the first Metal Gear Ac!d are reasonably subject to interpretation. Even though he does not know much about his history, those who have just been his companions are well aware of his abilities. As he makes his way back to the United States after a successful mission, his only expectation is that he will begin to recall his history when he sets foot on familiar ground. However, rather than having some time to do so, an FBI agent puts him and his companions into custody, leaving him with only one option to save his pals, which is to assist the agent with a mission of his own. Snake reluctantly agrees until he can figure out how all the pieces fit together and make sense of the situation.
This game, in contrast to the one that came before it, uses 3D cell-shading technology, making the game less realistic but more colorful. Additionally, you now have access to over 500 cards. The gameplay is essentially the same turn-based format as the first game. Still, it comes with various upgrades, such as the ability to undo your movements to a certain degree or move in real-time without losing moves on opening doors or crouching. Square Enix developed the original game. A new card form activates on its own when you play other cards and, in most cases, improves your action somehow. These cards are self-triggered.
The Metal Gear Ac!d 2 retail packaging includes a Solid Eye, a specialized pair of 3D glasses (a cardboard box that slips over the PSP; these are not the blue-purple plastic glasses; instead, they have lenses) so that players can experience the game with a 3D effect while playing. Additionally, you may utilize it to watch other Snake Eater and other movies as you unlock them in the game, giving you the impression that you are in a 3D area.
