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

Execution · Pure Mechanics
A by-the-numbers cover shooter testing only modest aim.

Execution · Practiced Mastery
A cinematic action game about Senua's journey through Norse hell.
Eat Lead: The Return of Matt Hazard leans Execution (Pure Mechanics); Hellblade: Senua's Sacrifice 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.
Eat Lead: The Return of Matt Hazard
Cover-shooter aim with generous margins
Hellblade: Senua's Sacrifice
Combat parries and dodges need timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Eat Lead: The Return of Matt Hazard
Parody enemies follow obviously scripted waves
Hellblade: Senua's Sacrifice
Bosses are scripted.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Eat Lead: The Return of Matt Hazard
Set pieces never change
Hellblade: Senua's Sacrifice
Minimal randomness.
Hellblade: Senua's Sacrifice leans a little harder on optimization, though the gap is small.
Eat Lead: The Return of Matt Hazard
Little to solve beyond weapon pickups
Hellblade: Senua's Sacrifice
Few build systems.
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.
