Dropzone Mars was made in 3 days for the Ludum Dare 41 game jam.
It is a mix of shoot-em-up and city builder. You must drop colonists on to the planet surface and defend them from unreasonable Martians trying to stop you from taking their planet. To negotiate with the Martians you have been given an auto-firing mounted cannon and a full supply of bombs.
Please let me know if you find any bugs or other issues.
