Necromunda is just NOT right for the amount of models we get down at once.
I'm waiting for Mort to throw these so-called Frag rules at me, but until then I am pondering simply hybridising either the 40k Assault system or perhaps a simpler one, using something like the Hero quest dice..
Everything else is pretty much perfect for the game, but fighting with necro' rules against 4+ Z's at once takes so bloody long.
Mankinds first mistake; Questioning why those around him, are dying.
You can find everything you need to know about Frag (+ a link to a PDF of the rules) Here
It should be pretty easy to make some fixed stats for the zombies and we can gather equivalent weapons stats from the original game - apart from that it's just a matter of applying your class rules to the new ruleset
~The ravings of a single mad Goblin is bad enough, but such a power-hungry, malice-filled creature as Mortis can never hope to be understood~
