If you spent any time in an arcade during the late 90s or early 2000s, you know the sound: the clack of a Sanwa joystick, the muffled thump of a cabinet's subwoofer, the specific chaos of a Knights of Valour screen flashing red while three strangers screamed at you to block. That era is gone, but the games aren't. H2 Interactive just dropped the launch trailer for the IGS Classic Arcade Collection on PC, and it lands on Steam August 13.
The collection bundles eight titles from International Game Systems, the Taiwanese developer best known for the Knights of Valour beat-'em-up trilogy. That series gets top billing here — Super Heroes, Plus, and Nine Dragons are all present — alongside Oriental Legend and its horror-tinged sibling Oriental Legend Spooky, the fighting game Martial Masters, the run-and-gun Demon Front, and the weapon-based brawler The Gladiator. It's a curated slice of IGS's arcade prime, the kind of lineup that usually stays locked behind MAME setups or overpriced eBay PCBs.
This isn't a straight ROM dump. H2 Interactive built in the modern concessions that make these playable in 2024: online multiplayer for up to four players on supported titles, save states, difficulty sliders, cheat toggles, move lists, one-button special move shortcuts, and fully rebindable controls. You can also swap between CRT-style scanline filters and clean HD output. The Switch version launched back in April 2023; the PC port has been a quiet "when" rather than "if" ever since.
Why the PC port matters now
Arcade preservation has been stuck in a weird limbo. ARC Raiders and other modern extraction shooters borrow the aesthetic, but the actual quarter-munchers remain legally inaccessible outside of sporadic Amazon Luna drops or Hamster's Arcade Archives line, which tends to prioritize Japanese heavyweights like Ace Combat series or Alien: Isolation over Taiwanese beat-'em-ups. IGS's catalog has a cult following — Knights of Valour in particular has a competitive scene that never fully died — but it's never had a legitimate, feature-complete PC release. This collection changes that.
The timing also tracks with a broader shift: publishers are finally treating legacy arcade code as a product line rather than a liability. Activision and AMD have both invested in emulation-adjacent tech recently, and the Steam Deck created a new hardware baseline where "runs perfectly on a handheld" is a selling point. A collection like this, built with save states and controller mapping out of the box, is practically Deck-verified before Valve even looks at it.
What's actually in the box
Let's break down the roster, because not all eight games land the same way:
- Knights of Valour: Super Heroes / Plus / Nine Dragons — The trilogy that defined IGS. Three-player co-op, branching paths, RPG-lite leveling, and some of the best sprite work on the IGS PolyGame Master hardware. Nine Dragons is the standout, adding a fourth player and a weapon system that changes combat flow entirely.
- Oriental Legend / Oriental Legend Spooky — Journey to the West beat-'em-ups with a dark fantasy twist. Spooky leans harder into horror imagery — Jiangshi, floating heads, blood fountains — and feels like a lost Capcom CPS-2 title.
- Martial Masters — A 2D fighter that sits somewhere between Street Fighter Alpha and Garou: Mark of the Wolves in feel. Deep combo system, parry mechanics, and a roster that leans into Chinese mythology. Never got a console port. This is the first time it's legally playable outside a cabinet.
- Demon Front — Metal Slug by way of Contra, with a pet system and branching routes. Co-op chaos at its purest.
- The Gladiator — Weapon-based arena fighter. Think Power Stone in 2D. Janky but charming, and the kind of local multiplayer game that starts fights in the best way.
Online support isn't universal across all eight — H2 Interactive specifies "selected titles" — but the Knights of Valour trilogy and Demon Front are the obvious candidates. If the netcode holds, this could resurrect a competitive scene that's been running on Fightcade and Parsec for years.
The preservation angle
There's a tension in releases like this. On one hand, you get legal access, quality-of-life features, and a reason for the rights holders to keep the IP alive. On the other, you're buying a curated subset — no Knights of Valour: The Seven Spirits, no Dragon Master, no DoDonPachi (different publisher, but still). The "collection" framing implies completeness that doesn't exist. And if the online population evaporates in six months, you're left with single-player beat-'em-ups that were designed to eat quarters, not respect your time.
That said, the save-state and cheat options blunt the quarter-munch design significantly. You can finally see the ending of Oriental Legend Spooky without feeding a cabinet $40. There's value in that.
What to watch for
The Steam page goes live August 13. Price hasn't been announced, but the Switch version retailed at $39.99 — expect parity. The real test will be the first week: netcode stability, input latency on non-Deck PCs, and whether H2 Interactive commits to post-launch support (leaderboards, spectator mode, rollback netcode patch). If this sells well, don't be surprised if a Volume 2 appears with the missing IGS titles. The hardware library is deep enough for it.
For now, mark the calendar. It's not often a lost arcade library gets a second life this intact.
