I would like to bring up an idea that I made a year ago (although this being a simpler version). Currently the game only have three Retro Mission waves without the variations, so why not add a new one?
These tanks can appear anywhere on the screen, up to a limit. They move and shoot at random direction, of course on the direction their cannon is facing.
The number of tanks that can be on the screen at a time depends on what loop currently is.
- Beginner Loop: 1-2 Tanks
- Intermediate Loop: 3-5 Tanks
- Advanced Loop: 5-8 Tanks
