About Last Defense: Asteroid Protocol
Last Defense: Asteroid Protocol by kronfeld is a free browser shooter with a one-line brief: defend the planet against endless meteor storms, and upgrade your weapons while you're at it.
Classic arcade defence — waves get worse, your guns get better, and the planet's fate is measured in how long your trigger finger holds out.
How to Play
Shoot incoming meteors before they hit the planet. Earn resources between waves and upgrade your weapons to handle the escalating storms.
Controls
Mouse – aim and shoot
See the original itch.io page for the developer's control notes.
Tips & Tricks
Upgrade early and evenly — a balanced arsenal survives longer than one big gun.
Watch the meteor trajectories, not just the nearest rock.
