# Claude Opus 5.5 Games: Neon Siege, Mortal Clash, Rooftop Sniper

Three browser games built with Claude Opus 5.5 and three.js — a neon arena shooter, a 1v1 fighting game, and a first-person sniper mission — all playable online with no installation.

## Description

A collection of three browser games made with Claude Opus 5.5 and three.js, playable online with nothing to install. Neon Siege is a sci-fi arena shooter: fight waves of robots in a neon arena, dash through bots, raise a shield to reflect enemy bolts, and pick up heavier weapons; an Overseer boss appears every fifth wave. Mortal Clash is a 1v1 fighting game against a CPU opponent where you pick a fighter and difficulty, then fight over several rounds with punches, kicks, blocks, specials, uppercuts and sweeps. Rooftop Sniper: Last Light is a first-person sniper mission at sunset over a procedurally generated city: scope in, tell armed spotters from civilians, correct for bullet drop and wind, and take out 5 hostiles within 3 minutes. Keyboard and mouse are recommended, in Chrome or Edge.
