BEFORE YOUR FIRST MISSION

Metal Slug. Ready for action?

Metal Slug is a side-scrolling run-and-gun series: move through enemy positions, rescue prisoners, collect weapons and reach the boss at the end of each mission. This browser collection brings together the six arcade releases shown above. The arcade games and their artwork are from SNK; AppsOverFlow developed this web player and its touch controls, save interface and local two-player connection.

Which game should I start with?

Metal Slug 1 introduces the core rhythm of moving, jumping and firing across six missions. Metal Slug 2 adds character choices and transformations, while Metal Slug X remixes that adventure with revised enemy and weapon arrangements. Metal Slug 3 has branching routes; its five main missions can offer different paths on later runs. Metal Slug 4 has six main missions, and Metal Slug 5 has five.

Use the game guides above for each title’s controls, mission structure and first-run tips. The 34-mission total counts main missions, not every branch as a separate level.

Keep moving. Keep playing.

Use the directions to move, crouch and aim, then combine them with FIRE and JUMP. Jump toward a Slug vehicle to enter; Down + Jump exits it. The SLUG shortcut sends that exit combination. Weapons and vehicles determine which aiming directions are available.

Automatic continues are on by default. When lives run out, the player supplies a free credit and continues. The bottom FIRE button becomes START or CONTINUE when needed and adds the free credit for you. You can also press Enter; character selection still uses FIRE. There is no coin purchase and no ad click is needed to continue.

Your screen. Your controls.

On a phone or iPad, rotate to landscape and open Options & Controls. Reduce opacity or button size if your hands cover the action, then choose Arrange Buttons on Screen to move each control. Portrait and landscape layouts are saved separately on this device.

Full width widens the complete arcade picture. Choose Original proportions if you prefer its original shape and accept side bars. Follow the illustrated mobile setup guide.

Save a run. Bring a friend.

Pause to save a state, then load it from the same browser on the same device. Save states are unavailable for Metal Slug 4 while its graphics restore issue is being fixed. Clearing browser storage removes saved progress. Previously downloaded game files can be available offline; installing the app does not download every game.

For two players, connect both devices to the same Wi-Fi or hotspot, exchange the host’s invite and the guest’s reply, and keep both windows open. Network isolation can prevent pairing; Bluetooth is not supported. Read the connection steps and limitations.

Collection audio was converted for this player; some sound effects may differ from the original arcade hardware. Save and continue help · Troubleshooting guides

PLAY TOGETHER

TWO-PLAYER CONNECTION

Connect both devices to the same Wi-Fi or phone hotspot. The host runs the game; Player 2 joins on their own screen. Bluetooth pairing is not supported.

Choose Host or Join to connect two players.

1. The host creates an invite and shares its code. 2. Player 2 pastes the invite and creates a reply. 3. The host pastes that reply to connect.

Keep both game windows open. Local network permissions, a firewall, or hotspot isolation can block pairing. Codes expire after five minutes.

Jump toward a Slug to enter it. Hold down and jump to exit. A fires, B jumps, C throws a bomb and D operates the Slug shortcut.
