## In short

Metal Slug X is SNK's 1999 Neo Geo run and gun, the reworked and faster version of Metal Slug 2. Marco, Tarma, Eri and Fio fight General Morden's army and the aliens across six missions, rescue prisoners for weapons, and drive the Metal Slug tank and other vehicles. Play it in your browser with keyboard, gamepad or an on-screen pad on phones, and switch on unlimited lives, bombs, invincibility or infinite time with the cheats button.

**How to control it:** Press Play and wait for the Neo Geo machine to start, then press Coin (V) and Start (Enter) and pick a soldier. Keyboard: arrow keys move and aim, Z shoots, X jumps, C throws a grenade. Phone: on-screen cross, A, B, C, Coin and Start. The magic wand button next to full screen opens the cheats.

**Metal Slug X** is Metal Slug 2 done again, faster and fuller. SNK reworked the 1998 game with new weapons, new enemy placements and the slowdown taken out, and many players think it is the best game in the series. Marco, Tarma, Eri and Fio fight through six missions of hand-drawn chaos, from the desert to a final battle against the alien mothership. It is SNK's 1999 Neo Geo game, and it plays right here in your browser with no download.
