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

Execution · Practiced Mastery
A free co-op top-down shooter about a marine squad purging alien-infested colonies.

Execution · Practiced Mastery
Robot-dinosaur hunting that rewards weak-point study and ranged precision.
Alien Swarm leans Execution (Practiced Mastery); Horizon Zero Dawn 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.
Alien Swarm
Top-down aim and friendly-fire discipline
Horizon Zero Dawn
Bow aiming and dodge timing matter.
Horizon Zero Dawn leans a little harder on reads, though the gap is small.
Alien Swarm
Swarm AI scripted by director triggers
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Alien Swarm leans a little harder on variance, though the gap is small.
Alien Swarm
Spawn timing varies modestly
Horizon Zero Dawn
Some loot and patrol randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Swarm
Class loadouts and route knowledge decide runs
Horizon Zero Dawn
Weak points, traps, builds fully 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.
