# The Block

> A GTA-style open world, built twice: first in Three.js, then rebuilt in Unity 6.

URL: https://roeesivan.com/projects/the-block
Year: 2026

## Overview

A small but genuinely playable 3D open world with a four-mission campaign. You can walk it, swim it, drive it, ride it and fly it. The project first shipped as a browser game on Three.js and Rapier, then I pivoted mid-project and rebuilt the entire game in Unity 6 rather than shipping a slice of it. Both builds exist; the Unity rebuild is the one whose source is public.

## What makes it interesting

- Two complete implementations of the same game: 175 TypeScript modules on the web, 219 C# scripts in Unity
- Four-mission campaign that runs through to a win screen
- Five traversal modes: on foot, swimming, car, motorcycle, jet ski
- Physics via Rapier in the web build, Unity's built-in physics after the pivot

## Technology

- Unity 6
- C#
- Three.js
