For anyone who knows how to play Hero of War by rise agianst, i need some help.

Im trying to learn off this video
and tabs.

In the video I cant tell if thats a C at first or a C/G. They sound too close together. Then is it an Em or E?

Another chord thing i found is the same chord shapes, but on capo 4.

The other one i found is the same notes as the capo 4'rd version, but without a capo so its like E, G#m, instead of capo 4 C and E.

So my question is, which version is the RIGHT version. like the one rise against plays.

Thanks for any help
