Maybe I'm expecting crime syndicates to have a unreasonable level of precognition, but I gotta say... I really can't see a situation in which killing the family of a guy named Mr. Vengeance is going to end positively. I mean, you have to think that with that name might get a little ticked off and have access to revenge-friendly weaponry. But hey, you have to kick off a rail shooter somehow, and you can't argue with what works. It's Mr. Vengeance: Act One by Russian developer TxGames. He'll roar. He'll rampage. He'll get bloody satisfaction.
