Doom II: Hell on EarthvsThe Callisto Protocol
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Mastering the double-barrel shotgun's rhythm while navigating scripted enemy ambushes across dense urban maps.
The Callisto Protocol
Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Doom II: Hell on Earth leans Execution (Pure Mechanics); The Callisto Protocol leans Execution (Pure Mechanics).
Doom II: Hell on EarthThe Callisto Protocol
Axis by axis

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Doom II: Hell on Earth
Super Shotgun and movement timing demand precise motor execution
The Callisto Protocol
Melee-parry timing and dodge-direction choices are the core skill
Reads0 vs 1

Doom II: Hell on Earth
All enemies are scripted; no opponent models the player
The Callisto Protocol
Mutants follow telegraphed scripted attack patterns
Variance3 vs 3
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Doom II: Hell on Earth
Ambush placements are hidden until triggered on first run
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
Optimization5 vs 5
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Doom II: Hell on Earth
Learning enemy placement and resource routes reduces every encounter
The Callisto Protocol
Weapon upgrades and credit management have limited depth
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.
