How do I get on the last mission in act2 gaurd at apr headquarters lets me in I go upstairs both doors locked no one there?

Look at your map, is there a mission icon on the APR headquarters. You may have finished all the APR missions or for some reason you may need to complete a UFLL mission first. This happened to me in ACT 1.

I thought I had a mission left, but it was from the other side. Also, check your journal and make sure it isn't telling you to finish up previous mission or underground mission.

Not entirely sure what part that is, but maybe this page of faqs for Far Cry 2 can help you out: gamefaqs.com/console/xbox360/game/944400....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
