Grand+bang+auto+download+best (iPad)

First, I should verify if Grand Bang is a real game. A quick search in my knowledge shows that Grand Bang isn't a well-known title. However, "Grand Theft Auto" is a major franchise. The user might have mistyped it. Alternatively, "Bang Bang" could be a game, but it's not as prominent. Maybe they're referring to multiple games: Grand (maybe a part of a title), Bang, and then auto download and best versions.
