Level 1 is free. No store. No launcher. No nonsense.

The city is made of physics.
He's made of attitude.

Aliens just invaded Los Angeles. They took the freeways, the beaches and all the good parking. Buster Kilroy is taking it back, one crater at a time. It's a retro boomer shooter that runs stupid fast, and nothing in it is fake. The whole world is built out of one living density field, so whatever you shoot actually breaks.

01

Every bullet carves the world

There are no painted-on bullet holes here. Every shot scoops a real chunk out of L.A. Make a hole. Make a window. Make a door.

02

Buildings come down

Shoot out the bottom floors and the whole tower comes down. If it lands on the aliens, that's called strategy.

03

A pocket black-hole gun

It's a singularity you can carry. It bends light around itself and swallows anything that isn't nailed down, plus a few things that are.

04

A strip club. Obviously.

The aliens took over the best club on the Strip. Buster takes that personally.

05

One very big alien boss

It's the size of a skyscraper and it thinks it owns L.A. It's about to learn what property damage means.

06

90s speed. Modern muscle.

Pixel grit on top, a real GPU physics engine underneath. No cutscenes you can't skip. Just run, gun and wreck.

WAIT, WHAT'S A ψ FIELD?

In Gary Alcock's Density Field Dynamics (DFD) physics, everything is made of one field, called ψ ("psi"). It's thick where there's stuff and thin where there isn't. Buster Kilroy builds its whole world out of that field. Bullets thin it out, and gravity bends it. That's why walls break like walls and the black-hole gun bends light like a black hole.

Words of wisdom.

  • Hollywood wanted a blockbuster. They got a Buster.
  • I don't do collateral damage. I do renovations.
  • That building had it coming.
  • Relax. I'm insured. Probably.
