SNK Corporation is celebrating the 30th anniversary of its run-and-gun franchise with Metal Slug Ultimate Collection, a comprehensive compilation heading to Nintendo Switch, Nintendo Switch 2, PlayStation 5, Xbox Series X|S, and Steam in 2027. Developed with M2, the package packs ten titles—including a legendary unreleased arcade prototype—alongside modern quality-of-life additions like online cooperative play and state rewinds.
Ten Titles, One Definitive Architecture
Originally debuting in 1996 on NEOGEO MVS hardware, the run-and-gun series earned a spot in arcade history through hand-drawn sprite work, chaotic destruction physics, and distinct audio cues like the booming “Heavy Machine Gun!” announcer line. According to official announcements from SNK, the upcoming 2027 collection represents the largest compilation in franchise history, consolidating nine core legacy entries and an unprecedented historical artifact.

M2 Emulation Engineering and Modern QoL Features
Handling the underlying code conversion is M2, a studio recognized for porting classic titles. M2’s implementation respects the original charm and operation feel while integrating modern software conveniences required by contemporary hardware.
Players navigating the compilation will have access to instant save and load states, alongside a real-time rewind mechanic that lets users roll back gameplay by several seconds.
Furthermore, select titles within the collection feature integrated online multiplayer capabilities. This allows cooperative sessions with remote players alongside global leaderboard tracking for score attacks. Additional offline modes include score challenges, time attacks, and the classic Combat School mode designed to train newcomers.

These include a global pixel mosaic project running through September 30, 2026, where user-submitted photos and illustrations are compiled into a massive anniversary art piece, as well as a themed AR camera filter available via official social channels through October 30, 2026.
For players tracking the physical and digital footprint of classic arcade revivals, Metal Slug Ultimate Collection bridges decades of hardware evolution—from NEOGEO cartridges to modern multi-platform architectures.
