A Real Multiplayer Game With Nothing to Install

Work laptop that blocks installs. A Chromebook. A machine that isn’t yours. VAULTREAVE is a full multiplayer dungeon crawler that opens in a browser tab and starts.

Search for something to play on a locked-down machine and you get the same list every time: Wordle, the Chrome dinosaur, minesweeper, a crossword. All fine. All two-minute puzzles.

This page is for the other case — when you want an actual game: classes, loot, a party of four, real stakes — and the machine in front of you will not let you install one.

What “nothing to install” actually means here

• No installer, no launcher. The game is the web page. Nothing is written to Program Files and nothing asks for admin rights.
• No account needed to start. One click puts you in. You can attach a password later if you want the character to follow you across devices.
• No plugin. No Flash, no Unity web player, no Java — just HTML5 canvas and a WebSocket, which every current browser already does.
• Works on the awkward machines. ChromeOS, a locked Windows image, a borrowed Mac, a phone. Same URL.

Be honest with yourself about the time

This is the part those listicles skip, so here it is plainly:

• Runs are real-time and online. You cannot pause. Close the tab mid-run and you have roughly a minute to get back before the run closes out and you drop what you were carrying.
• A run is minutes, not seconds. You choose the length — take the first exit you find, or push deeper for better loot and stretch it out.
• So: good for a lunch break, bad for the ninety seconds between two meetings. If you need something you can abandon instantly at zero cost, play a crossword. That is a genuine recommendation, not false modesty.

What you get instead of a puzzle

• Extraction stakes. Loot is not yours until you carry it out through an exit. Die and you drop it. Your camp stash is always safe.
• A branching exit. The blue door ends the run and banks everything; the red door goes one floor deeper — richer, meaner, one-way.
• Classes and builds. Distinct kits and skill trees rather than one avatar with a bigger sword.
• Co-op up to four. No friendly fire in party runs and downed teammates can be revived. Player-versus-player exists only in public matchmaking, which is opt-in.

Requirements, concretely

A browser with HTML5 canvas and WebSocket support — that is every current browser. No minimum GPU: it is pixel art on a 2D canvas, which is exactly why it runs on the hardware IT departments hand out. You can mute the tab and lose nothing mechanical.

FAQ

Do I need to install anything?

No. It is a browser tab — no installer, no launcher, no admin rights.

Can I pause?

No. Runs are real-time and online; closing the tab mid-run gives you about a minute to return before the run ends and you drop what you carried.

How long is one run?

You decide — leave at the first exit in a few minutes, or push deeper and stretch it. Leaving early is a strategy, not a failure.

What does it run on?

Windows, macOS, Linux, ChromeOS, Android, iOS. Anything with a current browser.

Is it free?

Yes, and no account is needed to start. Optional purchases are cosmetic or convenience only — nothing sold affects combat stats.

A note on where you play

Whether a game is appropriate on a machine your employer or school owns is between you and their acceptable-use policy. This page describes what the software needs, not what your IT department allows.
