Pixel Gun 3D is a 2013 first-person shooter game developed by Lightmap and published by Cubic Games for iOS and Android. Players choose from a variety of single-player and multiplayer modes, with single-player revolving around fighting enemies and multiplayer putting several players up against each other in competitions. These competitions range from attempting to get the most kills, to being the last person standing in battle royale. A single-player campaign is available, which puts the player in the role of an unnamed protagonist investigating the sudden "square-ification" of the world and the outbreak of numerous monsters.
