Chromium B.S.U.

A cargo ship, a fleet of robot fighters, and not one enemy may get past.

▶ Play Chromium B.S.U. free, in your browser, nothing to install

Chromium B.S.U. (Mark B. Allan, 2000; version 0.9.16.1) is a fast vertically scrolling shoot-em-up: you are the cargo ship Chromium B.S.U. and steer its robot fighter over a metal world, shooting down waves of enemy craft before they get past you. Every enemy that gets by costs a life.

This port keeps the original's game code number for number: the ship with its three guns and their ammunition, shields, super shields and repairs, the seven enemy types with their movement and weapons, the three levels with both bosses, the score, extra lives and the high-score list. The OpenGL scene, the chrome title, the textures, sounds and music are the original's.

Play it with the mouse as the original (click into the game to let it capture the pointer) or with the arrow keys and the keypad; space or the left button fires.
