Irem Collection Volume 2 Collector's Edition (PlayStation 4)

Before Metal Slug, there was GunForce. The Irem Collection Volume 2 Collector's Edition for PlayStation 4 brings together three pivotal Irem arcade titles, GunForce, GunForce II, and Air Duel, in a premium package limited to 999 individually numbered copies. This is the only physical edition available outside of Japan, period.

For PS4 collectors still building their library on the platform that defined physical game collecting for an entire generation, this release carries serious weight. GunForce II never left arcades until this collection. The developers who made it went on to create Metal Slug, and you can see the blueprint in every frame. Air Duel, a vertical shmup trapped in Japanese arcades for decades, finally reaches Western players on disc for the first time.

The Collector's Edition box features a magnetic latch and retro 4:3 art styling designed to evoke the era these games came from. Inside, you'll find a visual compendium doubling as game guide and art book, all three soundtracks on CD, a collector's coin from the five-volume Irem series, marquee stickers, reversible posters, a DIY reproduction of the GunForce SNES box, and reprints of original arcade flyers. Modern quality-of-life features like rewind and quick saves keep the gameplay accessible without compromising authenticity.

The PS4 disc era produced some of the best collector's editions in gaming history. This one belongs among them. Three games that shaped an entire genre, finally given a proper physical home.
