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 · Practiced Mastery
A top-down co-op shooter testing aim against waves of mutants.

Execution · Practiced Mastery
The template Far Cry: outposts, predators, and a tropical sandbox.
Dead Horde leans Execution (Practiced Mastery); Far Cry 3 leans Execution (Practiced Mastery).
Dead Horde leans a little harder on execution, though the gap is small.
Dead Horde
Top-down aiming against mutant swarms is core
Far Cry 3
Shooting and stealth fundamentals matter.
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
Far Cry 3
Pirate AI uses fixed alert patterns.
Dead Horde leans a little harder on variance, though the gap is small.
Dead Horde
Spawn directions add some unpredictability
Far Cry 3
Wildlife and outpost spawns randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Horde
Weapon choice and positioning plan survival
Far Cry 3
Skill trees and weapon mods quickly mastered.
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.
