What do you guys mean by "no losses"?

Yep, an Ironman mode would be cool - no reloads for the whole game. It'd be a different kind of challenge to the no losses challenge.

And to those who say that no losses is impossible, I used to think the same until I kept reading about all these guys achieving no losses playing KB:TL, so I thought I'd better try it to. It's surprisingly not as hard as you think - you just get into a different mindset where each fight is a challenge of its own, instead of trying to rip through the game quickly.
