About METAL SLUG X ACA NEOGEO

Released in 1999, this game is a revised port of Metal Slug 2. The developers focused more on the game engine and balancing the difficulty of the game. This iteration is part of the ACA NEOGEO series. The series focuses on games released on NEOGEO arcade systems. The developers of this port have focused on accuracy in recreating the arcade experience. Because of this, some of the quality of life features have been stripped. The port and the original Metal Slug games have a large following due to their stylish pixel art and raucous gameplay. The version on mobile has features that eliminate some of the frustrations associated with playing games on an emulated arcade cabinet.

METAL SLUG X focuses on two core elements: the emergent side-scrolling platforming and the resource management system, represented by sporadically placed resupply crates and vending machines. There are four playable characters: Marco Rossi, Tarma Roving, Eri Kasamoto, and Fio Germi. Each has unique attributes that grant slight bonuses against enemy forces. With quick and careful maneuvering, players are able to acquire Special Weapons that allow them to deal a great deal of damage against overwhelming enemy forces. Each level has POWs that are hidden in the environment. Rescue them to acquire a supply of ammo or a special weapon. Rescuing a POW contributes to the player’s final score.

The amount of equipment in Metal Slug Mobile is huge, and includes many of the most memorable weapons from the series. There are more conventional weapons, and then there are some really wacky and overpowered weapons (i.e. the Iron Lizard, which gives the player super speed, or the Big Laser Gun, which gives the player a really powerful sniper rifle). Each weapon has benefits and drawbacks, and it is up to the player to decide the best weapon to utilize in a given situation. The levels, while largely 2D, are highly interactive and destructible, which leads to the discovery of alternate routes and secret goodies.

While the varied and powerful weapons and equipment suit many different situations, some of the toughest bosses the game has to offer challenges the player to think outside the box. Bosses range from big hulking tanks to mechanical monstrosities, to aliens, to name a few. The great thing about the boss battles is that you’re usually not fighting them in a one on one situation, or at least not for long. Often times you’ll have to use the environment and vehicles to your disposal to survive. There’s a lot of competition going on worldwide. The game’s arcade nature lends itself well to global competition, as players can jump on, pick up and play, and instantly challenge people across the globe. It even gives you the option of controlling virtually how you play, giving you options for rapid-fire and other arcade-like settings. The game is really well suited for mobile gaming and is tons of fun!

The visual and auditory presentation remain a tribute to the hand-drawn art style of the late 1990s. The series is known for its humorous character animations, detailed background artwork, and explosive sound effects. The developers made sure to keep everything intact, from the frame rates to the specific color palettes used in the pixel art. The mobile optimizations don’t take away from the challenging nature of the game, as players can still experience true arcade difficulty if they wish. The game is a blast to play if you want to see how long you can last or if you want to take on the challenge of obtaining the highest score on the leaderboards. The game has worthy recognition for its timeless design and continues to be regarded as one of the best action games ever produced.
