## What it is
A tutorial series teaching how to build a Wolfenstein-like retro first-person shooter from scratch in Swift. It covers raycasting, grid-based maps, pathfinding, and line-of-sight techniques without requiring GPU or shader knowledge.

## Use cases
- learn to build a retro FPS game engine in Swift
- understand how Wolfenstein 3D raycasting works
- learn 2.5D game rendering without shaders
- prototype procedural map generation and pathfinding
- follow a step-by-step game programming tutorial
- build a first-person shooter for iPhone and iPad

## When to choose
- you want to learn game engine fundamentals from scratch in Swift
- you prefer tutorials that avoid complex 3D math and GPU programming
- you want to understand raycasting, pathfinding, and line-of-sight on tile grids
- you're targeting iOS or any platform that runs Swift

## When to avoid
- you need a production-ready game engine or modern 3D graphics
- you want to use an existing engine like Unity or Godot
- you need GPU-accelerated rendering with shaders
- you're not comfortable with Swift and Xcode

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: game-engine, graphics, simulation
- domain: tutorials, education
- platform: cross-platform
- tags: raycasting, wolfenstein-3d, fps, swift-tutorial, retro-gaming, game-development, swift, ios
