Published on June 22, 2008 if you get the extra 2 maps (free dl from the marketplace) you make it to dalton on the last mission. right before him is a check point. you kill him and get $75,000 watch the credits and then restart from checkpoint face him and get another 75,000 it takes about a min or so to beat dalton so this is a easy way to get lots of money. you can do the million dollars in about 30 mins if not sooner.
Published on March 18, 2008 Go through the whole game with a computer AI and u should get enough if u get all the cases(thus knocking out 3 birds with 1 stone) but if u dont get enought just load up a couple easy missions like 1 and 2 and get all the cases u can.
