Help a brother out

So ok /comp/ i need your help. I downloaded an torrent of my favorite computer game F.E.A.R, but thing is i had 3 different .iso images, i tried using daemon tools pro but everytime i mount it and try and play it, it still asks for the CD-ROM. Do i need all the files to be added together? and how do i do it?

Please help a /comp/tard out.

You'll be needing a no-cd crack to play a game without the cd (or iso in your case)
