When you get in to the decision, decisions part you can find extra items
like aid spray and handgun ammo it is most bullets.  How you get the
extra items is when you get to the last Scenario you will be in a
mansion like Resident Evil one and so remember the parts where you can
push a dresser around you can find dresser in the hall ways in Decision,
Decisions there will be dresser in just about all the halls and you find
extra ammo the reason I say this because I bet the game and had to use
the strategy guide for some of the game and these items where not in the
book.
