SharpShooter
Overview¶
SharpShooter is a hyper-interactive third person shooting game. Your job is to complete all three levels by shooting the targets using timing and accuracy. As the levels increase, you will face more moving obstacles that will block your shot and test your shooting expertise.
Gameplay¶
Controls¶
Using Navigation Switch or Joystick:
- Left = Move Left
- Right = Move Right
- Center = Shoot
