Ask a Tech-Priest
Greetings brother Enginseer. This is Castellan Revenatus of the Black Templars. A small question in relation to a modification to my power armor greaves - what do you think the feasibility would be of storing a mechanism within the greaves that would extrude a power blade from the knee plate? I've been pondering over plans for such a weapon, and Emperor forbid, do I find myself disarmed before the ravages of Chaos, I might have one last surprise weapon to bring the battle back in my favour..

Sister Enginseer.

I’ve given your proposal some thought, and I’m sad to say that I simply don’t know enough about the makings of a suit of power armor to tell you whether or not such a thing is possible.  The bulk of my training and expertise is in the design and production of stand-alone weaponry.  Bolters, plasma guns, that sort of thing.

I do know that power field generators are an exceptionally ornery form of technology that can be prone to some particularly violent breakdowns, which makes me wonder if installing one inside of the armor meant to protect you is really such a good idea in the first place.

There are other Explorators wandering around on the Warpnet.  You might ask one of them about it.
