Old PC Spaceship game name?
This game looks a lot like "Spacezero" in a sense that it had a black background with "stars", green outline of planets and a 2D feel. You start off with your ship on your planet, which was indicated by a square in the center of the planet with the same colour as your ship. The planet was surrounded by one or two Defense Towers, which also had the same colour as your ship somewhere on it.
The objective of the game was to conquer surrounding unmarked planets (without a coloured square of anykind) by landing on them for a short period of time, then your colour of square would appear in the center of the planet, which then would cause a Defense Tower to leave your home planet and travel to the new planet for protection against others who could try to conquer it.
You could, however, destroy and conquer other already "conquered" planets by destroying all the Defense Towers and landing on said planet, causing the square in the center to change to a new colour, corresponding to the new spaceship that landed on it.
Same thing goes for wandering Defense Towers, if you aimed right at the tip, I believe, you could conquer said Tower...or blow it up completely.
To win the game you had to destroy all other players, which meant for you to destroy all planets and Defense Towers of that colour so there would be no chance for them to re-spawn.
I believe there could be about 4 players in total, possibly manual or computer operated.
Im pretty sure to is not "escape velocity" or "naev", because the game was made just with lines like "asteroids" but they resemble to this game, just is older than them
Any suggestions and/or links would be very appreciated, I've been wondering this for a while now. Thanks in advance!
