I've been working on and off on a campaign for a while, based on the campaign mentioned in the story section. This is about 5-10 years after their last mission. The idea is that the Dominate makes a return to Virbius with new tech and starts a major offensive. Party of the edge the dominate has is new technology, officially it's recovered Archeotech, in fact...it's somewhat complicated.
The Dominate has formed an arrangement with the Logicians (Dark Heresy Group), the Logicians are given protection and material, as well as freedom to experiment within the Dominate holdings and in exchange they provide maintenance as well as tools and weapons against the enemy. Or from the Logicians perspective they get a bunch of beta testers and access to manufacturing that they wouldn't have normally.
I'm designing some new weaponry, armor etc. as well as some new units I guess I'm trying to figure out how ubiquitous the new weapons should be, not to mention his budget shock troops, basically glad warriors with some special modifications thrown in and kept tranquilized when not in combat. I can offer some samples of the new weapon and armor designs if you guys want, I am just trying to keep to a theme and also make it feel appropriate to the game.
