Two updates to the new Space Marine codex. If you would like to see them for yourself, they are located here.
But in case you have no desire to link jump... here are the massive amounts of changes.
1) Bike squads can swap out their bolt pistols for chain swords for free.
2) Command squads can now purchase specialist weapons without replacing any of their wargear.
So it is now possible to have a squad with 5 special weapons for a fraction of the cost it would take in the old SM codex. How cool is that?
Now, with this addendum, I am seriously considering putting the command squad back into my lists. What about you guys? Are they worth it?
