I got this game yesterday at like 9 or 10 PM and I've been playing it up to now. It's loving epic. I'm up to the mission from the rebels where there is a helicopter you have to get to, but I think I'm gonna stay and take more buildings and stuff. At this point the game is very hard anymore, except trying to take over SWAT bases. I have over 4000 dollars so supplies are easy to get, but I get pretty much everything I need from looting houses. I've been using the tek almost the whole time, and I've maintained over 2000 bullets throughout it all.
EDIT: Took the helicopter anyway and lost the girl I had with me the entire level D:
Also I played arcade and got 392,565 points.
