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 · Practiced Mastery
A co-op wave shooter where squads hold corridors against escalating specimen hordes for cash and headshots.

Execution · Practiced Mastery
A sword-and-gun action shooter rewarding combo timing mastery and careful upgrade investment against scripted demon hordes.
Killing Floor leans Execution (Practiced Mastery); Shadow Warrior (2013) leans Execution (Practiced Mastery).
Shadow Warrior (2013) leans a little harder on execution, though the gap is small.
Killing Floor
Headshots on zeds, kiting, weld timing
Shadow Warrior (2013)
Sword combos and gunplay require precise timing and input chaining
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor
Zeds follow fixed behaviours, never model you
Shadow Warrior (2013)
All enemies are scripted demons with fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor
Spawn waves randomise but quickly become familiar
Shadow Warrior (2013)
Upgrade drop randomness introduces mild run-to-run variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Killing Floor
Perk levelling, holdout spots, dosh economy solvable
Shadow Warrior (2013)
Ki power and upgrade tree investment form a meaningful build layer
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.
