Heavy melee is most certainly not unplayable, however it is inferior to heavy assault in all cases since the last update.
As far as the build, get 6 agility for sprint, enough intelligence for the best gear (you need 5 for some feats, it's debatable whether hammer should go 7 tho), rest str and con imo. For playing, it's pretty easy: just move behind a wall to force enemies to come to you, then wham them in the face. Sprint so you don't lose ap in the process. Hit and run is probably a good choice too, been a while since I've played the build so I don't know if it works in heavy armor or melee tho.
I think sledgehammer should be weak on purpose because... I mean come on, in an era with lasers and guns you're choosing to bash things with a hammer. Sledgehammer was deliberately very weak in fallout games as well, at least 3 times harder than an energy weapon character.
Thank you, but I know that too. You talk from a complete different Build here. As I wrote above, I am speaking here of a Heavy Melee Build with Metal Armor. This means 80-95% (depending on crafting Feats) mali to agility and less Movement Points, Evade, Dodge. Already the second step costs AP. And you can see i have in my Build only 3 Agility btw. What i mean as a "Walking" tank you can play only as Assault or with other ranged Builds but not melee.
Next problem is you have not allways the Option go behind a wall.
No offense. This is Underrail and not the Clumsy fallout. The developers put, fortunately, worth it, that you can decide for yourself what you preferred Melee, Ranged, or PSI.
@SadBaxter
this makes not a Big Difference i tested that (nimble and Armor Slooping) With Metal armors you become 65(armor slooping and nimble) 80(armor slooping) -95%(nothing) armor Penalty. Even with Armor Crafted from High Quality Items the Character is lame.
But that Sprint maybe help i dont know that this is not effected from armor penalty maybe i let Dexterity on 7 and go for agility 6. I test this. If i can get from other Ressources 8-12 Movepoints very High Tabis and Nimble and Armor Slooping i maybe can get enough MPs to play a bit better. As far as i rememberBut i think even after this Sledge Melee can need more love and Balance. Realy Powerfull is High Dexterity Stealth Knife Builds WOW with a bit CC through Though Control very nice. But have a Steath Character and like to tryd something different.
@hilf
Force Field helps not realy much.
Skillwise?!? I dont Posted how i use my skillpoints. But Attribut Points was Focused on Metal Armor and Melee thats true. I dont need Points in Perception as Melee and Willpower 4 and INT 6 is by far enough even if i use later Though Control (what is planed). Agility makes no sense with Metal Armor i though bevore SandBaxters Post but now i invest 6 Agility to get Sprint maybe that helps a bit.
