Alone Outside

This is a small top-down arcade shooter I made in Processing as a personal exercise to test out my A* pathfinding implementation. It started as a project for an exam, but turned into a fun little game that I’m pretty happy with.

The goal is simple: survive the first two levels, and then see how long you can last (and how high you can score) in an infinite third level. It’s fast-paced and chaotic, so good luck staying alive!

You’ve got three weapons to switch between:

• 1 – Pistol (your trusty starter)

• 2 – Machine gun (spray and pray)

• 3 – Shotgun (close-range destruction)

There are only two enemy types, but they’ll keep you on your toes as you dodge, aim, and blast your way through. Enemies drop helpful items you’ll pick up automatically by walking over them:

• MG ammo +32

• Shotgun ammo +6

• Medikit +2 health

• Heart +1 max health

All the code was written from scratch in Processing (no engine support), and I reused some of the assets from my other project, A Minute Outside, which you can check out on my itch.io page.

🎮 Controls

• WASD – Move

• Mouse – Aim

• Left Mouse Button – Shoot

• 1 / 2 / 3 – Switch weapons (Pistol/Machine Gun/Shootgun)
