Wow, I can't believe nobody noticed such an obvious flaw. Iban made it so that you don't get damaged as long as you have some energy. But, he didn't take into equation that the damage might be greater than the energy left instead of equal to it. Therefore, if you have even the slightest bit of energy you can survive a direct hit from a rocket launcher or even a tank shell. I'm not sure why he coded it the way he did but it's backwards. I suggest he take a hint from the v8 shielded player types.
[edit] he fixed it.
