PixelJunk Shooter

In PixelJunk Shooter, up to two players can control their own subterranean vehicles to rescue a number of surviving scientists trapped underground. Using their ships' missiles, players can defeat enemies and destroy weak rock to progress through the environment. In addition to rock and ice, players must manipulate three types of fluid (water, magma, and ferrofluid) in order to reach the survivors. Once each survivor is rescued or killed, players may progress to the next part of the stage.

If too many survivors are killed, players are forced to quit or restart the stage. The game has fifteen stages divided evenly among three "episodes", each episode ending with a boss encounter.

PixelJunk Shooter was formally announced during a 2009 pre-E3 press event on April 29, 2009. Originally referred to as PixelJunk 1–4, a 13-day contest was held in which fans submitted game title suggestions to Q-Games. The official title, PixelJunk Shooter, was announced on May 25, 2009. The simplistic name was received negatively by some fans to which Q-Games president Dylan Cuthbert explained that the name was chosen not only for its simplicity, but also because shooting is the game's central mechanic ("Shooting jets of magma, shooting streams of water, shooting enemies, missiles, lasers, plasma spread weapons etc.")

Several other titles were considered, including "PixelJunk Elements", the most popular submission. Ultimately, "Elements" was dismissed because "[it didn't] sound action-packed enough". The fluid mechanics are based on a particle flow simulation calculated using the Cell's Synergistic Processing Element or SPE.

The PlayStation 3 version of PixelJunk Shooter received "generally favorable reviews", just three points shy of "universal acclaim", while the PC version received "average" reviews, according to the review aggregation website Metacritic. The former console version was described by Eurogamer as "part retro videogame, part chemistry set; part Geometry Wars, part Zelda", while Game Informer called it "one of the best titles you'll find on PlayStation Network". Similarly, IGN's review called it one of the best PlayStation Network titles of 2009, as well as Q Games' "best work yet".

The same console version was praised by critics for its level design and unique physics; 1UP.com lamented that said console version did not include a "sandbox" mode wherein players could experiment with its various fluid substances. The music of High Frequency Bandwidth was also praised, described as "a funky, dynamic collection of upbeat trip-hop" by Eurogamer.

A PlayStation Home space for PixelJunk Shooter was added onto the existing Q Games "PixelJunk Museum" space on December 17, 2009. Upon entering the Museum, players receive articles of clothing unlocked by completing portions of PixelJunk Shooter. Completing the game 100% will unlock a complete scientist costume for players to equip their Home avatars with. The Home space features the virtual interior of the "Ers Piñita Colada", a space center seen in the main menu for PixelJunk Shooter.

PixelJunk Shooter 2 was formally announced by Q-Games on May 18, 2010. The title is the first full-fledged sequel to any PixelJunk game. Q-Games' Dylan Cuthbert said of the title, "it will have some features that are new to the PixelJunk series in general and will be bigger than the first game."
