Hey again,
I have posted some of the house rules in another topic but I was asked to seperate the changes so that they could be better compared against the existing core rules. This is basically a cut and paste job so their may be some grammar issues.
The first change is a fairly dramatic one as it relates to the bolter. It is clear to me that a weapon that is put in the players hand at the very beginning of the game should not outperform high cost specialized weapons in most cases. Some people may argue that on a shot per shot basis the plasma gun outperforms the bolter and they would be right some of the time. If, however, you take into account specialized rounds like the kraken variant and full auto that difference becomes quite absurd.
The bolter changes are as follows:
Bolter (Godwyn): Range 100M Damage 1D10+8 Penetration 4 Type (X) Special attribute Tearing
While this is an obviously significant decrease in potential damage output it does immediately make other weapons more viable. As for the fairly limited affect the weapon has against hard targets like a Space Marine, I feel this is true to the cannon as it has been stated that the Astartes power armour was designed to be able to take a bolter round at 20 feet. That said, with just 5 requisition the bolter can still do a decent job of putting even a Space Marine down. All bolter weapon types are similarly reduced in damage with the Heavy bolter having range 150M 1D10+12 penetration 5.
This is really an effort to bring the Deathwatch ruleset into line with the existing core books so that a rogue trader character could actually play with a marine.
