Files\SEGA\Condemned - Criminal Origins) and click on "view the player
data  folder".  After,  go to Save/Profile000/SinglePlayer. Select the
savegame  on  wich  you  want  to be invincible and open it with a Hex
Editor  (Hex  Workshop).  Once  it open locate this line (not very far
from the beginning)
