Irena Morales-RSV

SO i got my couzin rainbow six vegas(first one) and wev been playin it together and we are at the hoover damn level.the objective is track down irena morales and kill her.IM at the the part where i have to send jung to hack the computer and i have to go and kill irena(or at least thats what i think) so as soon as the terorists fast rope down, i go to the stais and as soon as i get to the second set it says you have failed to kill irena in time.it does this again and again and im so frusterated i want to whip my controller at my tv.Me and my couzin dont know what to do.any ideas or help would be greatly appreciatedIrena Morales-RSV
First be sure to kill all of the terrorists before Keller (or Jung ) mentions something about opening a door. Keller will tell Michael to stay with Jung while you (Keller), go upstairs and brain two terrorists. I highly recommend IGN's guide to R6V (I can't remember how many times i threw my controller).Irena Morales-RSV
i found the walk through but i cant find the 360 version of walkthrough.if you could supply me with a link that would be much aprreciated
we keep waiting and nobody says nothing and we just wait it out and then it says you have failed to kill irena morales. wev actually tried this for a few weeks now but me and my cuz are so frusterated that i think im gonna throw myself of the nevada damn
Yikes, sorry man. Just put this into your web browser.http://guides.ign.com/guides/815419/page_9.htmlI belive that the Irena part is near the very bottom.
