Alien vs. Predator
According to former Capcom artist Katsuya Akitomo, Capcom had plans to port the game to consoles back in the year 2000, but they were shot down by 20th Century Fox, who stated "that was a good game for its time, but that time has passed".

The game wouldn't recieve a release until 2019, thanks to the Capcom Home Arcade unit.
