CyberSec Emulator — CIACON CTF Game

Overview

A real-time multiplayer Capture-the-Flag game I built solo in Unity and shipped straight to the browser via WebGL for CIACON — an international CTF event that drew ethical hackers from around the world. No install: open the link, pick a room name, share it with a friend, and you’re playing head-to-head. It’s still live.

Highlights

• Unity → WebGL — built in Unity (C#) and exported to WebGL so the whole game runs in any browser, zero download.
• Real-time multiplayer via Photon — players who join the same room name compete live; the netcode keeps the session in sync.
• Made for a real event — the official CTF game for CIACON, an international conference for ethical hackers.
• Still playable — the WebGL build is hosted and online years later. Hit VIEW LIVE and enter a shared room name to go multiplayer.

How to play

Open the live link, set a room name, and have a second player enter the same room name — you’ll drop into the same match.
