Turtle: Invaders by TurtleP is a fixed-axis 2D shooter where bats come in and it’s your job to destroy them. Some will drop powerups that will aid–and some will harm. There are two game modes: Arcade and Endless. Arcade is about getting a general high score based on a small ‘story’. In this you’ll encounter a mega space bat, raccoon, and a phoenix. Once you’ve defeated the Phoenix, you win. You can play as various characters who have unique abilities as well. Try them all to find which one you like the best!
