The pinnacle of necromunda rulesets, this edition has cleared up much of the nonsense and bizarre quirk of the original rulebook. You probably didn't notice at the time if you were a kid playing, but as you grow older you see a lot of the clashes and imbalance and can struggle with some of the wording. This version clears much of that up, re-introduces the awesome catch fire rules, balances the skills table to a much more satisfactory entity, and my personal fave; makes the autogun a viable option by simply reducing the range of the las gun slightly.
The Necro players ruleset, this is written by Necromunda fans, for Necromunda fans. It stands on the shoulders of its giant predecessor and makes an already awesome game even more. Awesome! And it's freeeeeeee!!!!
The NCE Clears up a lot of the confusing wordings in the LRB, and offers some popular additions, like bringing back the Catch fire rules. If you prefer spending less time arguing and more time playing - the NCE is for you.
Better still - it's still being updated, so if you find something you think should be changed, drop by the NCE thread here on yaktribe:
