OASIS OMNIVERSE GAME RUNTIME

One Engine.
Infinite Worlds.

OGEngine is the shared game runtime that connects every OASIS world — shared quests, cross-game inventory, avatar SSO, NFT items, real-world discovery, and AR combat. Build once. Play everywhere.

The Engine That Connects Worlds

OGEngine is the game-layer backbone of the OASIS Omniverse — a shared runtime layer built on the WEB5 STAR API and WEB4 OASIS API that makes your game a first-class citizen of a shared, living multiverse.

When a player earns a sword in Our World, it exists in their OASIS inventory. When they find a keycard in a park, it opens a real door in ODOOM. When they gain karma by helping someone in real life, it flows into every connected world. OGEngine is what makes this possible.

Any game that integrates OGEngine gets instant access to the full OASIS player base, cross-game economy, persistent avatar identity, and the real-world discovery network — no backend infrastructure required.

OGEngine — the OASIS Omniverse game runtime
ARCHITECTURE

Three Layers. One Omniverse.

OGEngine is not a single library — it is the contract formed by three integrated layers that together give any game access to the full OASIS multiverse with zero backend infrastructure required.

CORE CAPABILITIES

Everything a Cross-World Game Needs

OGEngine abstracts the entire OASIS infrastructure so your game just calls the API — everything else is handled.

🎒

SHARED CROSS-GAME INVENTORY

Items, weapons, armour, powerups, and keycards persist across all connected worlds. Find a weapon in OQUAKE, use it in ODOOM. The inventory is player-owned via the WEB4 OASIS API.

👤

AVATAR SSO

One OASIS avatar identity across every integrated game. Players bring their name, reputation, karma, achievements, and NFT cosmetics wherever they go — no account juggling.

📜

CROSS-GAME QUESTS

Quests span worlds. Start a quest in Our World, gather an item in ODOOM, complete a challenge in OQUAKE — OGEngine tracks progress across all of them simultaneously.

⚡

KARMA PROPAGATION

Real-world and in-game actions earn karma that flows through every connected world. A player who helps their community in real life is recognised as a hero in-game — via the OASIS API.

💎

NFT ITEM MINTING

Weapons, armour, keycards, health packs, kills — any significant item or achievement can be minted as a blockchain-verified NFT. Trade on the OASIS marketplace or keep as proof of prowess.

🗺️

REAL-WORLD ITEM DISCOVERY

Physical locations in parks and cities hide digital items — keycards, weapons, armour, powerups. Players must visit them in real life to claim them, then use them in ODOOM, OQUAKE, and beyond.

🥽

AR COMBAT (COMING SOON)

Fight ODOOM and OQUAKE monsters in real-world parks using augmented reality. With AR glasses taking off, OGEngine will project enemies into your local park — actual exercise disguised as gaming.

⚙️

CACHING, BATCHING & MULTITHREADING

Built for performance. OGEngine's STAR API Client handles request batching, intelligent caching, and multithreaded delivery so your game stays fast even with cross-world calls at scale.

CONNECTED WORLDS

Games Already in the Omniverse

THE REAL WORLD IS THE LEVEL

Gaming That Gets You Outside

OGEngine bridges the digital and physical. Real parks hide real items. Real exercise earns real rewards. Real-world good deeds power up your character — in every connected world.

🗝️

FIND LOOT IN THE WILD

Keycards, weapons, armour, health packs, and powerups are hidden at GPS coordinates in parks and public spaces around the world. Visit the location in real life to claim the item — then carry it into ODOOM, OQUAKE, or any connected world. The same keycard that opens a door in ODOOM might have been sitting under a park bench all along.

🥽

FIGHT MONSTERS IN REAL LIFE

Coming soon via AR integration — ODOOM and OQUAKE enemies will be projected into your local park via augmented reality. With AR glasses taking off, you'll fight demons on your morning walk and level up on your lunchtime run. Real movement, real exercise, real gameplay — the park is your arena.

🌍

DO GOOD, POWER UP

The OASIS karma system rewards real-world positive actions — planting trees, volunteering, picking up litter, cycling, teaching, donating. Karma earned in the real world flows through OGEngine into every connected game, making your character more powerful the better a person you are.

STEP 01
Open the OASIS map and spot a nearby item cache
STEP 02
Walk, cycle or run to the real-world GPS location
STEP 03
Claim the keycard, weapon, or powerup to your inventory
STEP 04
Launch ODOOM or OQUAKE and use it — no import required
STEP 05
Repeat across the world, earn karma, level up your avatar
FOR GAME DEVELOPERS

Integrate Your Game in Hours

OGEngine exposes the full OASIS ecosystem through the STAR API Client — a C# Native AOT library that exports a native C ABI, giving your C or C++ game native-speed access to shared inventory, avatar SSO, quests, karma, and more.

Powered by the STAR API Client

The STAR API Client is written in C# and compiled with Native AOT (Ahead-of-Time) — it ships as star_api.dll / star_api.lib exposing a standard C ABI via AOT native bindings. Your C or C++ game links against it and calls star_api_* functions at native speed — no .NET runtime shipped with your game, no managed overhead at all.

The client acts as middleware between your game and the two OASIS API layers: WEB4 OASIS API handles identity, avatar profiles, wallets, and persistence; WEB5 STAR API drives quests, GeoHotSpots, objectives, and STARNET holons. The client locally merges quest progress so your game never makes raw HTTP calls.

Ships with offline mode and cloud resynchronisation, auto failover, auto load-balancing, auto-replication, built-in caching, batching, and multithreading. Runs on Windows, Linux, and macOS.
