The Idea
London Fallen is an open-world survival game set in a collapsed London. Players scavenge, fight zombies and each other, and build up gear across a map that is recognisably the real city — including the Tube.
Building a Real City
Rather than modelling London by hand, I wrote Lua scripts that generate it from OpenStreetMap data: buildings, parks and roads are placed from real map data, so streets and landmarks sit where they should.
Game Design
The design document covers the full loop:
- Loot — medkits, bandages, stims, armour plates, spare magazines, riot shields and supply-drop flares, each with a rarity and a place it can be found (floor, crate, vault or supply drop)
- Zones — danger ratings across the map, with the best loot in the most dangerous areas
- Movement — crouch, prone, slide and lean
- Progression — ranks, kill systems, a personal base, day–night cycles and an enraged horde every tenth night
Next
The map generation works; next are interiors, weapons and the zombie AI.
