Ammo = Life

A first-person shooter I built in Unity around a single rule: there is no health bar, and your ammo is your health. Every shot you take spends a little of your own survival, and the only way to heal is to go find more ammunition.

I made it as a constraint exercise, to see how much design pressure one honest rule could carry. The answer was a lot. Aggression and caution collapsed into the same dial, ammo pickups quietly became the real pacing tool, and accuracy started to matter more than fire rate. The build is rough and was never meant to ship, but it taught me to look for the one mechanic that does the most work and then trust it.

I wrote more about the design in a short post.
