Irem Collection Volume 2 Limited Edition (PlayStation 5)

Some collections preserve history. This one rescues it. The Irem Collection Volume 2 Limited Edition for PlayStation 5 delivers GunForce, GunForce II, and Air Duel on disc, limited to 1,500 individually numbered copies worldwide. Strictly Limited Games holds the exclusive on this physical release outside of Japan, so this is the only way to own these games on a PS5 disc.

GunForce kicked off the run-and-gun vehicle formula that would eventually become Metal Slug. GunForce II, its arcade-only sequel, improved on everything and was built by the team that went directly from this game to creating one of gaming's most iconic franchises. Air Duel, a vertical shmup that spent its entire life in Japanese arcades, gets its first worldwide console release here. Two out of three games in this collection have literally never been available on home consoles in the West.

The Limited Edition comes with a colorful game manual and the game on disc in an individually numbered case. Modern quality-of-life additions like rewind and quick saves are included, bridging the gap between arcade authenticity and modern convenience.

For PS5 collectors who care about what's actually on the disc as much as what's on the shelf, this is a historically significant release. The spiritual predecessor to Metal Slug, finally preserved in physical form. At 1,500 copies, it's accessible enough to chase but limited enough to matter.
