Collision Course is a GBA homebrew game inspired by Atari's classic arcade game Asteroids.
The early version of this game was was originally programmed for MS-DOS in the 1990's and was adapted to the GameBoy Advance to Game Boy Advance.
Features
- UFO.
- Sound mixing.
- High scores.
User guide
The top-left side of the display shows your current score and up to five of your reserve ships.
The goal is to destroy as much rocks as possible without colliding into them:
- Each large rock will fragment into two medium-sized rocks (20 points each).
- Each medium-sized rock will fragment two small rocks (50 points each).
- Small rocks disintegrate completely (100 points each).
After all the rocks are destroyed, more will appear after a few seconds in the areas indicated by the red arrows. Maneuver your ship out of the hazardous areas before they appear.
At random intervals, a violet UFO will appear and begin shooting at rocks and your ship:
- Destroying the UFO is worth 500 points.
- If your ship crashes or is destroyed by the UFO's weapon, you have two reserve ships ready to replace it.
For each 10,000 points you earn you will be rewarded with a new reserve ship.
If your ship is destroyed, and you have no remaining ships, the game is over.
FAQ
Q. I've destroyed all the rocks, but no more are appearing.
One or more rocks are moving along and just off the edges of the screen. Wait for a UFO to appear and watch the direction of its shots, being careful to avoid the ones aimed at your ship.
