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.

Wave-based co-op horde shooter.

Execution · Practiced Mastery
A loot-driven action shooter combining precise combat execution with deep weapon-crafting optimisation.
Killing Floor 2 leans Execution (Practiced Mastery); Shadow Warrior 2 leans Execution (Practiced Mastery).

Killing Floor 2
Headshot-focused aim and weapon-switching
Shadow Warrior 2

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
Shadow Warrior 2

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor 2
Perks, weapon synergies, money management
Shadow Warrior 2
Weapon modding and skill build optimisation form a deep solvable layer
