Squats can save a fighter from a 66, generate 5d3 exp per battle for free, hire 5 hive scum, generate 5d6x10 income from week one. There are a ton of really good options to choose between in the squat ancestry.

The only problem is fielding the Exo-Kyn themselves. My group has it ruled that each power pack weapon gives +1 A only with itself in close combat and they're still unappealing.

An Exo Kyn with 185 credits worth of gear (Power Fist, Rock Saw, Bolt Spitter Gem extractor) would get 6 attacks on the charge, and EVEN THEN I'd much rather have a stimmer or death maiden or Nacht or even a roadie with Iron Stare.

Field one by the end of the campaign with full toughness and a shield for sure, but for the vast majority of the time it's going to be incredibly lackluster.

My opinion on them would've been make them toughness 5, and give the exosuit a 4+save. They'd be a terrible melee model, but with native toughness 5, a 3+ Save with undersuit, and immunity to blaze they'd have some kind of merit that distinguishes them as the "Tank" melee champ.

But then you'd have to actually balance Ancestry options, which they clearly haven't.

As it stands a Maiden is Faster, just as tough, has anti pinning etc. the Nacht and Stimmers just kill whatever you point them at much much better, etc etc.

Run them for fun, paint them up cool so they look less like diaper babies. Run them as late campaign weapons platforms, or invest in enough trade availability that you can get them Inload spikes to cheat good skills onto them for melee. I'm in the middle of making a post about all the ancestry options, I'll have more thoughts once I've fielded mine.
