Our Expert Score

86/100

Metal Slug 4 is often overlooked in the series, but playing it again via the ACA NEOGEO port reveals it to be a rock-solid 'run-and-gun' experience. While it reuses many assets from previous games, it introduces the 'Metallish System,' a scoring mechanic that rewards you for rapid destruction, adding a nice layer of depth for high-score chasers. The newcomers Trevor and Nadia fit right into the chaotic world of the Peregrine Falcon Squad.

The action is as relentless and beautiful as ever, with the series' signature hand-drawn pixel art still looking incredible decades later. The 'Metal Slug' tanks are still a joy to pilot, and the boss designs are as screen-filling and imaginative as you'd expect. The ACA port's quick-save feature is a godsend here, as the difficulty is notoriously 'quarter-munching' high. It's a pure distillation of arcade action that feels great in short bursts on mobile.
