1: if you are in a stunt, the game makes a "ding" noise when you hit. If you are not in a stunt, what are you doing, mate?
2: More guns is good, but they have to have their own "job" for lack of a better word(or the energy to think of one). Most of the guns we have already come in pairs and are the opposing ends of the spectrum for their class. Ex. the Undertaker is more accurate than the Mac Daddy, however, you lose some damage and fire rate with that. That being said, what would be an opposition to the Persuader? Semi-auto, less accuracy, less damage?
3: Pretty sure this is possible for the most part, but some of those options could be made more easily accessible.
4: I've thought of suggesting wallruns in the past, but i'm not really sure it would fit into the rest of the game unless it transitions REALLY smoothly
5: There's already a teamplay mode, and its surprising how much a game of Wanted can change when half the server is now protecting instead of hunting.
6: IIRC there's at least 1 more character in development right now.
