Electronic Arts forced Crysys to change their name in 2011 due to legal issues with the game Crysis.
In Crisix shows, there's a variation of the wall of death called "Football of Death" (skip to 5:09 in the video). What happens is that a ball is placed in the centre of a pit, then at the signal, people will rush to kick the ball before moshing. This is also referenced in "Bring 'Em Into The Pit".
