Over the last few months, I've had a great pleasure to work with Grzegorz Kozłowski. We created the Messiah - Gothic Mitrailleuse.
The Messiah is a sacred weapon used by the high priests in their battles with the infidels. Handling this weapon requires superhuman strength. The Messiah works in two ways. In mitrailleuse mode, it spits a wave of bullets from its organs forged to barrels and plays the canto of doom. In cannon mode, it fires lead balls filled with holy plasma.
