So here's two revision ideas.
'Battleskunk' Mobile Gun Walker <- not valid according to word of discord, posted for later reference.
It is a fact that certain over-enthusiastic souls, on seeing that there was a cannon mounted on a walker, attempted to see if they could aim and fire the cannon while the walker was in motion. It is also a fact that, to the surprise of few, the actual accuracy of an infantry cannon mounted on the highly unstable firing platform of a legged walker ranges somewhere between 'Oopsies' and 'Non-existence'. To the surprise of more then a few this didn't actually discourage the mentioned over-enthusiastic souls enough to get them to stop. Instead, what they decided was that they needed something easier to aim. As such, they took the Skunk and re-designed the front firing platform to carry a swivel gun they 'requisitioned' from the navy instead of the infantry cannon, allowing for a lighter, easier to maneuver gun primarily loaded with grapeshot to make the the continual issues of actually aiming at anything more then a short distance away no longer an issue while sheltering behind the still existent gun-shield when enemy fire shows up.
While certainly inferior to a purpose designed close assault walker, the so called 'Battleskunk' does show a certain amount of promise.
'Beast' Animal Soul Engine
It is a fact that while it is possible to construct engines that function off the power of animal souls, the current generation is... well, shoddy to put it bluntly. That forces certain limits on the overall size of any designed walkers. These limits highly irritate certain engineers, whom decided to get around them by making a version of the engine which was less shoddy and less likely to randomly break down while still generating the motive power that an animal soul should be able to generate.
