Traveller - Delta 3 is very definitely Down again!

I'm really pleased that Delta 3 is Down, an adventure for Traveller is finally back in print as a PDF. This was the first adventure I wrote that was published by BITS, and it has been out of print for quite some time. It's now converted to Mongoose Traveller.

It's set before the Fifth Frontier War, and has a Zhodani Admiral crashing onto the mainworld in the Emerald system on the border between the Consulate and the Imperium. The admiral understands all the Zhodani naval strengths along the border, along with the contingency plans. 

Written for convention play, the opening is perhaps a little bit of a railroad as it drives towards their ship crashing, but once the characters are down on the surface it becomes more of a sandbox as they try to escape the escalating Imperial response. 

Once again, Andy Lilly helped to expand this up with more detail. We released it as a TAS publication rather than Traveller Compatible as it's very much tied into canon (and skimming the new Fifth Frontier War line from Mongoose, I don't see anything that should cause a major issue in compatibility). 

The idea for the scenario came when I was in hospital after a minor operation and I was reading the first GURPS Traveller Alien Races book, Zhodani & Aslan. I decided that I really wanted to explore the Imperium from the perspective of the Zhodani; what would the feudalist, capitalist Third Imperium be like to someone who grew up in a culture of care and trust, where people know their place in society and that unhappiness is treated as a mental health issue and treated with psionic techniques. I liked the courier ship presented in the rules and the scenario grew from there.

It proved popular - and sometimes fatal to the characters - at conventions. Remembering that Traveller has a deadly combat mechanic is important. For example, if you're in a G/Truck, don't try and risk getting shot by a starship defence laser, because the outcome is messy.

There are several ship designs included in the book; a conversion of the Zhodani courier, an Extended-Duration Imperial Scout, and an interdiction satellite. 

The cover was a gorgeous collaboration between Andy Lilly and the late, great Jesse DeGraff. 

Overall, it's a scenario that I'm really happy is available again and I hope it brings fun to Travellers who get to run or play it.
