Gaming site ModDB.com has removed a game called School Shooter: North American Tour 2012 after receiving negative press and threatening mail.

The school shooter game is a modification of the popular game Half-Life 2. The aim is to kill as many innocent students, teachers and staff members as possible.

In a blog post explaining the removal of the controversial game, ModDB founder Scott Reismanis wrote “we disagree with the mod but at the same time believe in freedom of speech.”
