Even with all the pressure, the controls stay smooth—movement, jumping, and shooting feel responsive and natural—so you’ll stay locked in for long sessions.

Face giant tanks, strange mutated creatures, and mechanical monsters. You’ll need to study their attack patterns and exploit weaknesses, testing both your tactics and your nerves. When you finally defeat a screen-filling boss, the payoff is incredibly satisfying—boss battles here are widely regarded as classic moments in gaming history.

Gameplay & Performance

In this game, you play as a commando battling multiple enemy types, including terrorists, zombies, and aliens. The title includes a fresh storyline and several new additions.

Alongside Nadia and Trevor, the game introduces a dual submachine gun setup. It also adds a monkey transformation system, giving players another way to change the flow of combat.

This is an unofficial mobile port that brings arcade-style controls to touchscreens in a way that aims to feel smoother and easier to handle. It also supports gamepad controls.

All in-game content is included, including hidden elements and Easter eggs, plus a careful transfer of the soundtrack. Music is presented in a way that lets players enjoy the work of Toshikazu Tanaka, known for compositions in the Metal Slug series.

Helpful Tips

The core control scheme stays familiar: use a lever to move, and use buttons to attack, jump, and throw grenades.

A key improvement is the addition of a new special button, which removes the need to press attack and jump at the same time—helping prevent unintended “super” actions from triggering at the wrong moment.

Weapon note: the newly added dual-wielded heavy machine gun hits hard, but ammo drops quickly—so don’t waste bursts.

Each character plays a little differently. Pay attention to things like grenade behavior and melee attack style, then try multiple fighters to find who fits your playstyle.

The game also includes a Metal System. You can earn medals based on your score within a set time after collecting badges (blue/gray). After finishing a level, you receive extra rewards depending on how many medals you earned—so you may even end up with more medals than the prisoner.

However, medals reset after a player death, just like with the prisoner system—so stay cautious and avoid unnecessary risks.

Final Words

With these options, players can experience this classic arcade favorite in a more comfortable way—making it a great pick for both hardcore action fans and long-time Metal Slug supporters.
