As simple as most Einstuerzende Neubauten songs, just two bar-lengthy chords 
(written in brackets). Bass goes like that:

   (Gm)              (Cm)
G:|--------(5)------|-----------------||
D:|-3---------------|-----------------||
A:|-----------------|-3---------------||
E:|-----------------|-----------------||

When the thumping goes harder, bass just follows the rhythm:

   (Gm)              (Cm)
G:|-----------------|-----------------||
D:|-3-3-3-3-3-3-3-3-|-----------------||
A:|-----------------|-3-3-3-3-3-3-3-3-||
E:|-----------------|-----------------||

(x) - "ghost note" - can be omitted.

Thank you.
