It's horrific. An online video game that re-enacts the Sandy Hook Elementary School shooting drew sharp criticism this week from family members of one of the victims.

The game, titled "The Slaying of Sandy Hook Elementary School," allows players to follow shooter Adam Lanza's path through Newtown, Connecticut, on the day of the Dec. 14, killing his mom, and then shooting and firing his weapon on students and teachers.

Relatives of Victoria Soto, a teacher who was killed in the shooting, condemned the game on Twitter , telling the game's creator: "Please tell us how playing a game that recreates how Vicki died would be beneficial?"

But the creator, Ryan Jake Lambourn, says players are encouraged to contact their state governor and representatives and keep up to speed with gun legislation.

Connecticut Senator Richard Blumenthal is demanding that all online vendors take down the video game.

Blumenthal says the video game that depicts the attack on Sandy Hook Elementary School last December is a vile game that mocks common decency.  

The senator says that with the one-year anniversary of the attack fast approaching, it's shameful that there are still people out there who would seek to exploit the tragic event.
