To the sordid history of troll shock games that includes Kindergarten Killer, Pico's School and Ethnic Cleansing, add The Boston Marathon: Terror on the Streets, "developed" by two members of the notorious "Lolokaust" group of trolls. In it, you play as a marathon runner attempting to jump over pressure cooker bombs.
Sigh.
If you must see the game in motion, a demonstration is on YouTube.
