Cheat:

     Here  is  a  way  of getting infinite energy and health. When you
next  come  across  a  first  aid  kit or battery on the floor, before
picking  it up make sure that you are holding something in your hand -
anything  from ammo clips to severed limbs. If you now double-click on
the  item,  you  power  or  health will be restored, but the item will
remain  on  the  floor,  effectively providing the infinite health and
energy promised.

Tips:

     Level  Three: Shoot the cameras in the maintenance levels to open
the  door blocked by Shoden, and use the severed head from the lantern
room in the retina scan to open the door behind.

     Level  Six:  Explore the groove Delta for a Targeter, Alpha for a
shield and Beta for a Nav unit and goodie-ridden passage.

     Later  Levels:  Enter  the  self-destruct code from CPU rooms; be
wary  of  DETOX patches; organise your MFD; and dispatch Ed Diego with
the Magpulse.
