There is only one letter difference and the typography of the game logo also resembles. The main character name, Shelly Harris, also bears a lot of resemblance with the name of the bands songwriter, Steve Harris. A lawsuit was filed in California demanding a ban of the name whilst claiming damages. Reason enough for 3D Realms to change the name to Ion Fury this summer. The game was launched in August, however the logo has largely remained the same.
