Following a lawsuit launched against The Tetris Company, THQ has acquired the rights to publish Tetris on the Xbox 360 in territories outside of Japan (i.e. North America & Europe). THQ alleged that The Tetris Company breached their contract, preventing the publisher from releasing a version of the classic puzzler for the DS. Instead, Nintendo swooped in and published one of the best installments of Tetris to date.
According to THQ's financial filings, a settlement was reached, which included the Xbox 360 publishing rights.
