Hi Frank. I just posted a message but it has not appeared so here I go again.
Your walkthru of QOS is absolutely brilliant, I played it on my PS3 but had to use this forum to find the help I needed and I am glad I did, its very lively and interesting forum, I will use it again. I hope you will write more walkthru's in the same format, no frills just aims and achievements. WELL DONE!
