The Basic Challenge mode of Aim Trainer is designed as a quick and easy aim training exercise. It requires no parameters to be put in and is a bit simpler when compared to the other modes. In this mode, the player is tasked with shooting at the appearing targets with three lives displayed in the right corner of the screen. Each target that the player doesn’t hit will cause a life to deplete. Once the player neglects to hit three targets in total, the game ends and the stats of the round are displayed. While missing the targets won’t cause the player's lives to go down, it will affect the player's stats.
