head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Time-loop assassin puzzle where each day refines the perfect chain.

Optimization · Pure Optimization
Solving fixed 2D guard layouts through precise sound management and upgrade-optimised routing.
Deathloop leans Optimization (Pure Optimization); Mark of the Ninja leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Deathloop
Gunplay and slab timing required.
Mark of the Ninja
Precise ledge timing, sound-cone avoidance, and kill windows demand input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deathloop
Visionaries scripted; PvP invasions rare.
Mark of the Ninja
Guards investigate noise on scripted logic; no player profiling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deathloop
Loadout drops and Julianna invasions randomize.
Mark of the Ninja
Guard placements are fixed per level; no RNG disrupts routing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deathloop
Time-loop puzzle - chaining kills is solvable routing.
Mark of the Ninja
Distraction sequencing, upgrade paths, and ghost-score routing are solvable
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.
