It's exaggerating what you can do to show that it's both legit and how far you could take it. They probably also wanted to stress that there was never any lag or flaws despite all the explosions going on.
and this game is too addicting. I went on to play for thirty minutes, ended being an hour thirty. I finally got my assault rifle the way I want it (until another 20 or so levels when I unlock a new gun) but I still need to level up the revolver, which is proving to be a chore since I suck with it and I need 100 kills. I have 13.
