I´m doing this with the HUD off. Well, I started with it "on" and saw that the hidden manuscripts were not, you know, hidden, so I went for HUD "fade". In this mode the HUD comes up whenever you press LB. Then I noticed that the objectives were not that hard to figure out anyway (observation skill will do) so I changed it to "off". The only problem with "off" is that there is no way to see how much life is left, although Alan does make a sound indicating he is low.
