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 · Practiced Mastery
Wave-based co-op horde shooter.

Execution · Practiced Mastery
Soulslike shooter where procedurally rolled campaigns randomize bosses and loot.
Killing Floor 2 leans Execution (Practiced Mastery); Remnant: From the Ashes 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.
Killing Floor 2
Headshot-focused aim and weapon-switching
Remnant: From the Ashes
Souls-style dodging fused with sustained gun accuracy.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor 2
Scripted zeds, no adaptive opponent
Remnant: From the Ashes
Bosses are scripted movesets despite feeling adversarial.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor 2
Spawn waves and trader loot vary
Remnant: From the Ashes
Procedurally rolled worlds, bosses, and item availability.
Killing Floor 2 leans a little harder on optimization, though the gap is small.
Killing Floor 2
Perks, weapon synergies, money management
Remnant: From the Ashes
Build crafting and learned boss patterns converge to mastery.
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.
