I played Vice City when if first came out, and loved it- but I simply stopped when I got to one mission. I don't recall the name, but it involves shooting out the windows of stores. I'm going to replay it, any tips? It always seems like each window takes ages to break... I'm not above using codes to get out of that damned mission, so if you think any would be useful, let me know.
I've never used a motorcycle, if you have infinite sprint I don't think it could be as fast- but I may try it anyway to see. It sounds interesting. I've never had any trouble getting them to break right away with a 9mm uzi or MP5, just run from one store to the next and fan them with bullets. The main thing I think is getting to the mall fast, and having a good pattern. Start at the very top or very bottom of the mall, by an escalator and then just run around the entire first floor, which will bring you back to the stairs where you started and do the same thing upstairs. As long as you don't waste lots of time getting to the mall or running up/down/back/forth randomly in the mall, you should easily finish with lots of time to spare.
