Cheat: No Damage

     Note:  This  cheat  involves  editing  a game file. Always make a
backup before proceeding.

     The  file  you  will be editing is easy.var (for Easy difficulty,
use other files for other difficulty settings). It can be found in the
"25  to  life\data\var" folder. First, right click the file and select
properties.  Uncheck  "read-only"  and  click  OK.  Open the file with
Notepad  or Wordpad. Locate the line that reads "AI2PlayerDamage 0.14"
and  change  0.14 to 0. Save the file. Now when you play you will take
no  damage  from AI characters. You can also adjust to a higher number
if you want to allow yourself to take some damage.
