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 · Pure Mechanics
Sequel continuing the Alma horror story with mech sequences and slow-motion combat.

Execution · Pure Mechanics
A bullet-hell action-adventure testing dodging and platforming precision through hostile arenas.
F.E.A.R. 2: Project Origin leans Execution (Pure Mechanics); Luna Abyss leans Execution (Pure Mechanics).
Luna Abyss leans a little harder on execution, though the gap is small.
F.E.A.R. 2: Project Origin
Aim and slow-mo trigger discipline
Luna Abyss
Bullet-hell dodging and platforming demand precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Enemy squads are clever but scripted
Luna Abyss
Enemies are scripted, not adapting to you
Luna Abyss leans a little harder on variance, though the gap is small.
F.E.A.R. 2: Project Origin
Minor spawn and cover variation
Luna Abyss
Some randomness in bullet patterns and encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Learning arenas and ability usage
Luna Abyss
Weapon and movement mastery reward planning
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.
