Project Valkyrie is:
A Three Month Mod started as a team-building exercise wherein we quickly ground out a deliverable within a three month time frame. From there we would move along to more complex and original projects. Somewhere along the way though, we became very attached to our little mod, and diverted all of our efforts from our large-scale, big concept project to complete Three Month Mod not only with quantity, but also quality.
