Wild stuff. I am personally not looking fwd to having to shoot my way down many flights of cramped, narrow stairs in an office building in that Goldberg mission. Well, no, I am, I am, but I would like to think there's another way out of that firefight. I would just end up being a dumbass and going for the windows and doing a belly flop like you could potentially get away with in an older GTA, but surely can't anymore.
I guess jumping for that chopper wouldn't work either. But would look cool.
