Annhexation gameplay — a hex-based 4X strategy map
Annhexation Early access

A turn-based 4X strategy game I built from scratch — custom WebGPU engine, eight civilisations, no install. Play it in your browser right now.

You can play the game online.

While working on the 8-bit console I got the itch to create a twin stick shooter. There’s some Geometry Wars in this and some Jeff Minter with a dash of Pink Floyd.

Best thing to do is just go play it rather than me describe it! But there is a YouTube trailer and images below and I’ve written about it building it too.

Its open source and you can grab the source code here.

Annhexation gameplay — a hex-based 4X strategy map
Annhexation Early access

Forty-two years after I first started programming, I built a browser-native 4X from scratch — a custom WebGPU engine, eight civilisations, and an AI opponent I'm still teaching to play. No install, no sign-up. Play it right now.

Built by James Randall — tool-maker, system builder, and occasional cyclist. Walking the hills with my four-legged friend when I'm not building worlds.
