Steam's lack of quality control has once again caused the firm to find itself in hot water.
Brazil's Public Ministry of Federal District and Territories (MPDFT) has started looking into both Valve and Steam, as well as the developers of a project called Bolsomito 2k18.
The title has players cast as someone going around trying to stop communism, and is "inspired by the current Brazilian political climate".
"On tense days with an election extremely polarised in progress, a game developer has created a game that promises controversy," reads the document. "In the animation, the player places himself in the skin of the PSL to the Presidency of the Republic, Jair Bolsonaro, and earn[s] points by killing militants, gays, feminists and members of landless movements."
This is the latest controversy surrounding a game released on Valve's platform following in the footsteps of a title that sees users taking on the role of a school shooter and, um, AIDS Simulator.
