The company that owns Tetris has publicly threatened the White House over a game that plays like the classic block-stacker, saying it takes copyright infringement “very seriously.” The Trump administration launched an online arcade of MAGA-themed retro games on Thursday, including a Tetris-style "Build the Wall," subtitled “Zombie Border Siege.” In the game, players stack falling blocks into a southern-border barrier and try to keep cartoon zombies and other figures from crossing.
