Orbital Defense Program is a tower-defense game with some roguelike elements.
You play as the Commander of the ODP, and your objective is to protect the earth against an alien invasion, by allocating resources to upgrade the functions of the ODP, making strategic decisions and executing some actions in real time. The main means of defense is the Orbital Cannon, which fires automatically at aliens.
This is the release of the demo version with:
- 15 waves.
- 4 alien ship types
- 10 Unique events
- 8 available modules
- 10 available upgrades
The composition of the waves, number of aliens and some of the events are randomised for each run. In the future I plan to add even more variety of options, in order to make each run a different experience.
