Update (Wed 27th Sep, 2023): Sadly, the excellent 90% discount for Marvel's Avengers now seems to have suddenly ended, with the game going back up to its standard price of $39.99 / £44.99 on the Xbox Store.
Original story (Mon 25th Sep, 2023): This week marks the end of an era for Marvel's Avengers, which will officially be getting delisted across all platforms on September 30th. This means you'll no longer be able to buy the game from the Xbox Store after that date.
Until then though, the game has received a massive 90% discount, meaning you can purchase the Marvel's Avengers Definitive Edition for just $3.99 / £4.49. In our opinion, that's a no-brainer!
