The gun is loaded, but there are not as many shells as we would like, so turn on the economy mode so that there is enough for all enemies. You in the game Gun Idle will run evil black creatures that have appeared from somewhere in the underworld. To pass the level, you need to kill everyone, so shoot accurately. The muzzle turns very easily, even too much, sometimes it gets in the way. In the foreground, you will see three properties that can be leveled up using earned seconds. Choose what you need most in the first place: the rate of fire, damage, or increase the number of seconds gained in Gun Idle.
