The 2D game, previously known as PixelJunk 1-4, has players blasting through caves to release pools of lava-quenching water.
Q Games ran a public naming contest to come up with a title for 1-4, with Shooter being picked as the winner for its simple descriptive quality.
"The most popular name suggested by a long shot was PixelJunk Elements, but we decided that it didnâ€™t capture the shooting side of the game well enough and at the worst people might think it was a game about the weather," said Q Games president Dylan Cuthbert.
"'Depths' almost became the chosen name but our producer at Sony Santa Monica, Deborah Mars, sounded like she had a lisp when she said it, so we dropped that one early on," he added. "We needed to choose a name everyone can enunciate."
