Pretty decent stuff,and ends like the many do.
One plot hole,though,or maybe just something worth pointing out.
10 deaths before,another 10 deaths later,but not including the survivour?,and then the newest set of 10 plus our main protagonist...except the North Korean soldier,which would be 11 and over the supposed limit,unless he's not applicable since the others were South Koreans.
And the poncho fella seemed like a different party to the rest of the fellas,unless that was just part of the collective that did them in.
Otherwise,worth the quick read through.
