head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
A bullet-hell shooter testing precision dodging through dense scripted patterns.

Execution · Pure Mechanics
Mastering the double-barrel shotgun's rhythm while navigating scripted enemy ambushes across dense urban maps.
Bullet Heaven 2 leans Execution (Pure Mechanics); Doom II: Hell on Earth leans Execution (Pure Mechanics).
Bullet Heaven 2 leans a little harder on execution, though the gap is small.
Bullet Heaven 2
Dodging dense bullet patterns is the whole game
Doom II: Hell on Earth
Super Shotgun and movement timing demand precise motor execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bullet Heaven 2
Bosses fire scripted patterns, not adaptive
Doom II: Hell on Earth
All enemies are scripted; no opponent models the player
Doom II: Hell on Earth leans a little harder on variance, though the gap is small.
Bullet Heaven 2
Item drops add minor randomness
Doom II: Hell on Earth
Ambush placements are hidden until triggered on first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bullet Heaven 2
Character and weapon choice optimize survival underneath
Doom II: Hell on Earth
Learning enemy placement and resource routes reduces every encounter
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.
