Sounds like the remaining 500mb left on my hard drive won't be enough
...but that's probably because there's been nothing like that in a GTA game before.Characters will work together during missions, and you can switch between characters mid-mission to fulfill different roles. For example, during a chase sequence you can pilot the getaway helicopter as Trevor, snipe pursuing pilots as Franklin, or fire an assault rifle as Michael.
Side-missions similar to Taxi, Ambulance, and Vigilante will return, but “probably not identical” to those from previous games.
I despised playing 4 with the slow frame rate and crap physics
Crap physics? The way IV plays physics wise is what makes it epic for me lol.
