Earlier, I wrote a post detailing a bunch of power-suits for use in a TL10 frontier setting with hostile alien beasts. In this post, I will be building the next step: TL10 combat walkers. These will be built using the method described in Walkers and Power Armor.
Paverguard's strider series are quite a bit lighter than true mecha, but are still quite heavy and have cockpits rather than being mere suits, providing a huge strength boost and heavy armor. At weights below 3,000 lbs or so, Paverguard recommends its signature battlesuit line. (That's the natural point at which this armor method begins to be more effective than the battlesuit formula)
