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 · Pure Mechanics
A top-down shoot-em-up testing aim and dodging against scripted alien waves.

Execution · Pure Mechanics
Sequel continuing the Alma horror story with mech sequences and slow-motion combat.
Earth Defense Force leans Execution (Pure Mechanics); F.E.A.R. 2: Project Origin leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Earth Defense Force
Top-down shooting and dodging are the core demand
F.E.A.R. 2: Project Origin
Aim and slow-mo trigger discipline
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Earth Defense Force
Enemies are scripted waves, not adaptive
F.E.A.R. 2: Project Origin
Enemy squads are clever but scripted
Earth Defense Force leans a little harder on variance, though the gap is small.
Earth Defense Force
Enemy spawn patterns add some unpredictability
F.E.A.R. 2: Project Origin
Minor spawn and cover variation
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Earth Defense Force
Weapon management and positioning aid survival
F.E.A.R. 2: Project Origin
Learning arenas and ability usage
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.
