01About

Man the twin flak cannon of a destroyer and clear a hand-drawn sky. Fire proximity-fused shells at biplanes, fighters, bombers, gunships and jets, shoot falling bombs and sea-skimming missiles out of the air, and switch to night vision or thermal to spot stealth bombers and UFOs.

Ammo is limited, so every shot counts. Chain kills for combo multipliers, pick an upgrade after every wave, earn medals, rank up and stock your ship in the workshop. Then take down the alien mothership in wave 10 and see how long you last in endless mode.

02Features

01

15 kinds of targets

Biplanes, fighters, bombers, a zeppelin, gunships, jets, missiles, drone swarms, kamikazes, stealth bombers, UFOs and the mothership.

02

10 waves + endless

Scripted waves with a boss finale, then an endless mode that keeps escalating until your hull gives out.

03

Night vision & thermal

Some enemies only show up in green phosphor or white-hot thermal. Switch views mid-fight to find them.

04

Every shot counts

Limited ammo and an active reload with a perfect-reload zone turn every burst into a decision.

05

Ranks, medals, workshop

13 ranks, 7 permanent perks, a daily supply drop and a daily challenge keep you coming back.

06

Death cam

The shot that sank you is replayed in slow motion from its own point of view, then the ship goes down in a crane shot.

04Development notes

01 · Rendering

A pencil renderer, written from scratch

Every object writes to a G-buffer. One full-screen pass turns it into a drawing: edge detection with wobbly, boiling double lines, light-dependent cross-hatching, coloured-pencil fill and paper grain.

02 · Audio

Sound that is synthesised, not played back

Weapons, explosions, engine loops with Doppler, ambience and the adaptive score are generated live in Web Audio. Only the announcer speaks from recordings.

03 · Pipeline

Models built by code

Every aircraft and the ship are generated by headless Blender scripts, so a tweak to a wing is a one-line change and a rebuild.
