Pixel Gun 3D is a first-person shooter game with a pixelated art style reminiscent of Minecraft. Players are able to select up to six weapons, ranging from traditional guns such as sniper rifles to flamethrowers and spellbooks. Additional equipment, such as gadgets that serve a specific purpose (like grenades or a jetpack), pets that fight alongside the player, or armor with unique abilities (such as allowing double jumping) can be utilized by the player in battle as well. Players can also create their own assets in the game, such as skins, as well as join clans with other players. The game features different modes, including single-player campaign and survival modes, local and online multiplayer, and a battle royale mode. In the campaign, the player is placed into a level and tasked to kill every enemy inside, defeating some sort of boss at the end. In survival mode, players fight off against an endless wave of enemies for as long as possible. Multiplayer modes put the player up against others worldwide, competing in different objectives such as attempting to get the most kills. In battle royale, a large number of players are placed onto a large map that gets smaller over time, with the last player standing winning. Players can receive in-game items by either unlocking them through playing the game normally, or by purchasing them with in-game currency. The in-game currency itself can be purchased with real-world currency, with prices ranging as high as $100.

In the game's campaign, an unnamed protagonist investigates the sudden "square-ification" of the world, which occurred at the same time as an outbreak of various monsters. Attempting to solve both mysteries, the protagonist travels across different worlds after his house was attacked by zombies. He traverses throughout the countryside and reaches a facility known as Area 52, where a researcher tells him the outbreak originated from a portal in an elementary school. Going through the portal and traveling to a different dimension, he meets an unnamed survivor who travels alongside him before the group reach the Hell Castle, where a dragon takes them to another world. The protagonist and survivor reach a metropolis and discover the cause of the "square-ification," the result of an error in the game developer's code. After using virtual reality to fight the error (known as "The Bug"), the protagonist becomes trapped within the internet and becomes The Bug. After floating around the internet, he is found by a ship under attack by droids. After he defeats the droids, it is revealed that the protagonist is trapped inside of an online game known as Cubic Revolution, and the protagonist begins plotting on how to escape the internet for good.
