Valve have disabled purchases for a Steam game made by one 31-year-old Cole Tomas Allen of Torrance, California, who allegedly tried to shoot up the White House Correspondents’ Dinner at the Washington Hilton hotel on Saturday. The game in question, Bohrdom, was published in December 2018, and is described on its store page as “a skill-based, non-violent asymmetrical fighting game loosely derived from a chemistry model that is itself loosely based on reality”, with a multiplayer mode that takes inspiration from quantum physics.
