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 top-down co-op shooter testing aim against waves of mutants.

Execution · Practiced Mastery
First-person parkour against zombies, especially terrifying after dark.
Dead Horde 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.
Dead Horde
Top-down aiming against mutant swarms is core
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.
Dead Horde
Enemies are scripted hordes, nothing adapts
Dying Light
Zombie AI scripted, non-adaptive.
Dead Horde leans a little harder on variance, though the gap is small.
Dead Horde
Spawn directions add some unpredictability
Dying Light
Night-hunter encounters bring randomness.
Dying Light leans a little harder on optimization, though the gap is small.
Dead Horde
Weapon choice and positioning plan survival
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.
