The song is in G minor.  And I like playing these chords:

Gm7             Ebsus2  
Whos in bunker, whos in bunker? 
Bbsus2             Ebsus2             Ebsus2
Women and children first and children first and children etc.

|--1--1--5--1--1--|
|--1--1--6--1--1--|
|--2--3--5--3--3--|
|--0--0--0--0--0--|

You can repeat those throughout the whole song!
