Aiight, I don't think anybody will respond to this & I've already searched everywhere but I'm on my way to 100% completing this so:
IRON Raider in Greece 35
Complete Greece without dying.
IRON Raider on Lost Island 40
Complete Lost Island without dying.
Since both are divided in different sub-levels my stupid question is: If I play one/two level e.g. Lost Island: "Natla's Mines" + "The Great Pyramid" successfully WITHOUT DYING
but die in "Final Conflict", do I have to play all Lost Island chapters
again or only replay the last one I died in order to get this achievement!? Thanks for the reply.
EDIT: Found it out by myself. The answer is: No, you don't have to replay the other sub-levels. As soon as you finish one level WITHOUT DYING it counts forever. So you only need to finish up the remaining levels. Happy hunting!
