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

Execution · Practiced Mastery
A twin-stick shooter testing aim and crowd control against zombie hordes.

Execution · Practiced Mastery
First-person parkour against zombies, especially terrifying after dark.
All Zombies Must Die! leans Execution (Practiced Mastery); Dying Light leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
All Zombies Must Die!
Twin-stick aiming and dodging hordes is the core skill
Dying Light
Parkour traversal and melee timing demanding.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
All Zombies Must Die!
Zombies swarm on fixed AI, nothing to out-predict
Dying Light
Zombie AI scripted, non-adaptive.
All Zombies Must Die! leans a little harder on variance, though the gap is small.
All Zombies Must Die!
Drops and modifiers add some randomness
Dying Light
Night-hunter encounters bring randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
All Zombies Must Die!
Crafting weapons and quest routing builds power over time
Dying Light
Crafting, blueprints, skill trees 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.
