Building comparison
head to head
HelldiversvsUnderMine
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Helldivers
Optimization · Practiced Mastery
Twin-stick co-op shooter precursor.
UnderMine
Optimization · Systems & Chaos
An action roguelike about mining gold, dying, and upgrading the next peasant down.
Helldivers leans Optimization (Practiced Mastery); UnderMine leans Optimization (Systems & Chaos).

Axis by axis
Execution6 vs 5
Helldivers leans a little harder on execution, though the gap is small.
Helldivers
Twin-stick aim and stratagem inputs
UnderMine
Pickaxe-throw combat and dodging in real time
Reads1 vs 0
Helldivers leans a little harder on reads, though the gap is small.
Helldivers
Scripted enemies, no real reads
UnderMine
Dungeon creatures are scripted
Variance6 vs 6
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Helldivers
Random spawns and patrol pressure
UnderMine
Random layouts, relics, and curses each run
Optimization7 vs 7
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Helldivers
Loadout combos and stratagem chains
UnderMine
Relic synergies and permanent meta upgrades compound
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
