 The much hyped DeathWalk feature went through five incarnations  before arriving at the shipped version. The original design had  death wraiths attacking in the environment after the player died in  battle, but this wasnt fun in closed environments. In the second  incarnation, this was changed to always take place in an open  environment called the underworld. The player would have to stay in  the center of the arena while death wraiths attacked and tried to  knock the player off the arena until Tommys spirit power restored  to full. This proved too complex a process to ship. Fighting the  death wraiths to restore life was added in the third version. The  third version also added the concept of Tommys physical body  falling back to the natural world, however it would rise back up if  the player stopped shooting wraiths, bringing a final death. This  also proved too complex, and was not fun for testers. The fourth  version was pretty close to the final version of the game. Tommys  body now lowered itself to the physical realm on a timer, and the  player would shoot spirit wraiths until Tommy was fully lowered, and  health wraiths quickly after. In the final version, this was changed  to shooting both health and spirit wraiths while Tommys physical  body is restored.
