Your hero or villain can still die and the meter runs out, but you only need to kill four people for four points to unlock the hero or villain again. Change the options to the following: Best Player, 4 Points, and the time for the hero to become available to 4 seconds. Go to the options and choose the 'Hero' selection. Additionally, select Instant Action mode, choose your levels, but do not launch. You can start the game selecting the hero, and when you die you can pick them again immediately. Select 'Hero', then change the options to Best Player, Time Limit 1 second, and the time for hero to become available to 'Always'. Select Instant Action mode, choose your levels, then go to the options menu before you start.
Note: This is the 2005 game by Pandemic Studios, not to be confused with the 2017 game Star Wars: Battlefront 2 by EA DICE.
