Spawners are enemies in Going Commando. They are light-gray and pink-colored creatures, with short stubby legs and four protrusions near their sole orifice on the top. Both of their legs and protrusions are tinted a dark brown. Spawners have no discernible mouth, eyes, ears, or other notable features, but they possibly detect nearby enemies and offspring through vibrations with their many legs. It otherwise does not have any direct indication as to how the identical spawners can spawn different species.
Two spawners were encountered in Vukovar Canyon, Barlow, along the "Scout the ruined machinery path. One was found a hidden cave containing many Gadgetron Hounds of Cuddly Death, which they themselves would also spawn, while another was found along the main path. Several were also fought in the mining area on planet Tabora, during "Find a way out of the underground tunnels" and "Return crystals to mystic", as well as in the large surrounding desert, where they spawned multiple spitting dune crawlers. A few were also found in the west end of the desert that spawned mutant sandflies. Finally, several were encountered in the distribution facility on Smolg, during "Explore the docked ships" and "Traverse the Warehouse", where they spawned the local species of Grulch.
As their name implies, the spawner's sole function is to spawn new creatures, up to a limit of six at a time. If the total number of species that it spawns exceeds or is equal to that number, then it will be docile and harmless. Once that number does go below six, then they will instantly release more enemies continuously until defeated. Spawners do not move from their position and will die from a single hit from any weapon, but defeating them can be difficult if one does not use any (or want to use) any weapons that can adequately penetrate through their spawned offspring fast enough to take out their source. The Pulse Rifle, Minirocket Tube, and Spiderbot Glove can be useful in picking them off, but alternatively, any other form of overwhelming force is sufficient.
