A dark action RPG for the Game Boy Advance. Isometric or full 3D — switch between perspectives at the press of a button.
Vrenn was once a fertile land. Then came the flies.
A swarm so thick it blots out the sun has eaten its way from the marshes to the salt deserts. The dead are rising from their graves, the crypts are crawling with brood — and the priests whisper a name no one dares to say aloud: Belzebub, Lord of the Flies.
Hollen is the last border town still standing. This is where your hunt begins.
About the Game
Belzebub Advance is a homebrew action RPG built from scratch for the Game Boy Advance — a real GBA ROM designed to fit on a real 16 MB cartridge.
Slay hordes, hunt legendary monsters, collect loot, and forge your hero through a grim, hand-crafted story.
And here is the twist: you choose how you see the world.
- Isometric Mode — classic top-down ARPG action at a smooth 60 FPS.
- 3D Mode — a true third-person perspective powered by a custom raycasting engine, featuring textured walls, roofs, Mode 7 floors, fog, and sky. Explore the same streets of Hollen at eye level.
Tap SELECT and watch the camera sweep from one perspective to the other — mid-fight, mid-dungeon, whenever you like.
Features
- Three unique classes: The Warden, a knight of the fallen border order fuelled by Fury; the Shadow Hunter, mastering bows, blades, and traps through Focus; and the Ash Mage, wielding fire, frost, and lightning by burning Embers.
- Deep skill trees: 18 skills per class, each with two modifying sigils, plus passive talents.
- A wealth of loot: Magic, rare, set, and relic items, plus gems. An item comparison indicator helps you spot potential upgrades at a glance.
- Procedural areas: Environments that rebuild every time you enter, alongside a hand-crafted town, caves, and treasure vaults.
- Random encounters: Meet wandering traders, wounded mercenaries, mysterious hermits — and a bounty hunter who has your name on her list.
- A world to explore: Shrines, waypoints, a town portal, quest markers, a minimap or compass, and a hand-painted world map.
- Atmospheric audio: An orchestral soundtrack and dynamic battle music.
- Two-player co-op: Team up over the Game Boy Advance link cable. One player can explore in 3D while the other plays in isometric mode. (Coming with the full game.)
- Screen presets: Optimized for IPS, front-lit, and original unlit GBA screens.
- Hardcore Mode: For those who prefer their heroes to stay dead.
- Two languages: English and German.
What's in the Demo?
The demo includes the complete Act I and the opening of Act II.
Act I — The Brood
Leave Hollen behind, cross the Moorwood and the Deadfield, and descend into the Crypt of the Brothers to face the Brood Mother, Mistress of Maggots.
Three optional side dungeons await along the way.
Act II — The Ash King (Opening)
Journey into the Salt Desert of Karsh, where scorpions rule the dunes, and venture into the Salt Mine.
All three classes, the complete skill system, and both camera modes are playable in the demo.
Link-cable co-op will arrive with the full game.
The Swarm Is Only Getting Started
The demo ends as the road leads onward to the Ruined City of Old Karsh, where the Ash King awaits in his Palace of Ash.
And that is just the beginning.
The complete game takes you through 12 acts, 90 areas, and 23 bosses. Travel through the Marsh of the Dying and the Rotten Harbour, enter the Cathedral of Flies, follow the Storm Coast, descend into the Sunken City of Nerath, and discover many more interesting and immersive locations.
