The first Space Invaders videogame to allow the player to move their ship all around the screen was Space Invaders Infinity Gene (Taito, 2009), released for the iOS platform on 27 July 2009. In all previous iterations of the game, starting with the arcade cabinet launched in 1978, players could only move left and right. The design of Infinity Gene was inspired by Charles Darwin's theory of evolution, and the game opens with a quote from the man himself.

It was highly acclaimed by critics, with Eurogamer's Simon Parkin describing the game as the series' "crowning achievement" and awarding it nine out of 10.
