Love the system. There are a few rules that I have added to fill in some gaps.
One of the few areas that GURPS has no rule for, I posted the question on the sj games forums and me and a few others came up with these ideas.
I am a Prop Whore
Heres a Prinatble Police Rport XLS including SearchWarrant, Autopsy Report, Suspect list and Narrative Supplement.
Here is a Printable MOCK DD214
GURPS and Game Balance:
And as an added bonus, a Zombie module that I've been working on. You may not be able to use it 'whole cloth' but you may find bits of it useful in your campaign. We had a helluva lot of fun with this one. Note that it is not yet complete, but I will be adding the final maps soon enough. You'll also need the ZombieCS.Zip file that contains the zombie builds I used (as worked out here).
Althoguh not a complete adventure, Quarkstomper from the boards was kind enough to loan me some notes regarding GURPSifying the old Thundar the Barbarian Cartoon. Its not a complete adventure, and the notes are a mess, but with these in hand you have a firm head start on your first adventure in the thundar univesre that Ends At the Kenedy Space center facing down Gemeni and a Fire Breathing Space Shuttle!
I hope to add stuff periodically as Im inspired and as its asked fo me. Keep watch here and on the SJGames forums for updates :)
