Adapting The Morrow Project to GURPS

[midnight77]

So, for those who don't know, The Morrow Project was an old RPG where your characters were frozen in the late 70s-1989 to be awoken 3-5 years after a nuclear war to help rebuild the US. Unfortunately, there was an accident and the project fails to awaken its members, allowing for you to be awoken 150 years later.

I am attempting to do some conversion of this to GURPS. Most is straightforward, but there are several things that I need help on.

The first is one of the weapons: the RH202 20mm cannon doesn't seem to have GURPS stats that I could find. In addition, in the game it comes with both HE and AP rounds that need separate damage values.

Another issue is the Resistweave, which is a form of body armor in coverall form that is resistant to small caliber bullets and knives. I need to know what sort of DR it should have.

Unfortunately, GURPS Vehicles 4e is not out yet, or else I could make the necessary vehicles for the game, so I will have to improvise that as well.
