Lumberjack

There are quite a few self-proclaimed "master inventors" among Hollow Raiders. Their most proficient skill is taking proper second-hand industrial materials and transforming the abandoned combat machines left by Public Security in the Hollow into not-so-proper personal creations.
High-speed chainsaws, toothed circular saws, hydraulic industrial arms... After simple assembly and rough welding, these common materials are stacked together to form a rare and dangerous piece of machinery.
To make it run smoothly, the creator has "thoughtfully" removed the safety restrictions of the machine and, based on its rugged appearance, named it the Lumberjack.
No one knows how long the Lumberjack can run stably.
Perhaps, at any moment, it could suddenly go berserk, swinging its high-speed rotating chainsaw and spikes with unmatched horsepower, launching an unstoppable logging fest that no one dares to stop.
But... this near-mad combat mode might just be the best modification outcome the creator had in mind.
"Why call it a 'Lumberjack'? There's no wood to chop in the Hollow, right?"
"Yeah, that's why it's so angry. When it starts up, it's reckless..."

In combat, the Lumberjack constantly shifts its chainsaw's form to perform fluid combos, using its mounted wheels for swift movement. When enemies are out of reach, it fires saw blades to chase them down from a distance.
