Monster Truck - Power Of The People Chords & Tabs

Tuned to D Standard

I've only figured out part of the intro so far but I thought I'd write down what I have. 
It would help a lot if people could contribute in the comments!
[ Tab from: https://www.guitartabs.cc/tabs/m/monster_truck/power_of_the_people_tab.html ]
This is the first tab I've ever tried to actually figure out myself, so there is 
probably a bunch of mistakes.
