Fun Run is a mobile app where you race against real people, trying to get to the finish line first. When, you do this, however, you can use saws,Rocket,Lightning,Punch them through a box, use a Trap and other bloody ways for them to ''die''. However, when you die in the game, there is some mild blood but you automatically regenerate. This game is fun but has some violent content. Mild blood and you can kill each other's characters in the ways I listed above. It is ment to be comedic, but still, violence is violence. Some mildly inappropriate names can be entered ( I have seen some usernames with lots of bad words) and you can become friends with random people and chat with them (however I never chat with random people online) but that is only in the "Friends" option in the game if you become friends with random people. I do not think you can do that in the "quick play" option in the game. This game is fun, but because of some mild cartoon violence,iffy language, and some serious privacy concerns, fun run is iffy for twelve and up.
