If you’re an urban-focused crew you’ll need to purchase (or acquire) a few extra bits and pieces. Try and buy a dodgy second hand van for keeping your junk in and to take to spots. It could also double up as a way of generating speed.
For those tighter urban features that’ll score you maximum legitimacy points on the interwebz, you’ll want a bungee and/or drop in ramp/winch to generate speed. Lights and a generator are pretty handy if you’re going to be shooting at night, and of course you’ll need all the basic stuff like shovels and water to drink/bind snow with.
