Welcome to ArcadeOS — a whole arcade in your pocket, and now on your wrist. 68 hand-picked original games, each one its own cartridge: full 3D open worlds, kart racers, ninja action, gothic pinball, paper-craft RPGs, sky shooters, momentum platformers, run-and-gun, belt brawlers, puzzle boxes and rhythm. Every game is an original creation in the spirit of the golden age of consoles — drawn in code, scored with real chip audio, and built to be picked up in seconds. HALLOW EDITION Worlds, not cartridges. LOOSE KEYS: HALLOW HOLLOW is a full 3D open city under an orange moon: take any car, hearse, helicopter, plane or boat, outrun a three-star heat system, fly a fast jet off a military airfield, land an airliner at the international airport, and work a phone full of jobs — in a city full of witches, skeletons, horsemen and the odd creature from an 1818 novel. At its heart is HOLLOWMERE, a haunted theme park with a graveyard coaster you can actually ride, a drop tower, and a lagoon parade with fireworks on the hour. MODS ship with it: god mode, every weapon, flight, moon gravity. IRONBARK is a heavyweight momentum platformer: an armored-bark brawler and a glider partner tag-teaming through an industrial jungle of barrel-cannon chains, mine-cart runs and hidden bonus rooms, drawn in fine-pixel art. GLIMMERGLASS KEEP rounds it out — a free-roam 3D collect-a-thon built over 25 nights of iteration. All three have original soundtracks synthesized live inside the app. CHERRY EDITION 23 games rated five stars by our testers before they shipped — look for the cherry on the cartridge. Highlights: Reefjack's lantern-tide run-and-gun, Thornhollow's gorge platforming, Quiet Falls' suburban-oddball RPG, Emberline's three-winter family saga, Cascabel's commedia brawler, Ironvane's vertical shooter, and Crestline GP's speedboat regatta. APPLE WATCH ArcadeOS ships with an Apple Watch app. Six games are built for the wrist and the Digital Crown: Redline Ridge (crown hops lanes, hold to burn), Sunstrip (crown steers, tap to shift), Ironvane (crown flies, hold to charge, tap to call your wingman), Truck Simulator (roll the crown and the truck drives itself — steer, hold to brake, deliver the cargo), Haywire (a horse loose in a farmyard full of physics: buck, jump, cause chaos) and Cairnglass (a crown-controlled falling-sigil puzzler). Runs on its own — no iPhone needed nearby. FEATURES 68 games — every one with its own hand-crafted cartridge art Home screen: your games as icons, with folders you make yourself Gold-star collection: beat a game, earn its golden seal.
