Lots

not too bad

Games about 3GBs total now.
Well worth it though.
Lots to do other than BR, theres Racing, battle racing, and Drifting now(i know weird, but still fun), theres a city map with actual building taller than 3 stories and that you can climb all the way to the top of and snipe people from. 
It also has a lot of freebies too and they changed it up a little so its easier to earn new non freebies. 
they also updated the world graphics a little too... unfortunately character graphics arr still waiting for an update lol.
