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

Execution · Practiced Mastery
An open-world revenge tale where a new shapeshifter hunts Alex Mercer through plague-zoned New York.

Execution · Practiced Mastery
A twin-stick action shooter testing aim and crowd control against scripted hordes.
Prototype 2 leans Execution (Practiced Mastery); Warhammer 40,000: Kill Team 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.
Prototype 2
Power-swapping combat and traversal demand decent dexterity
Warhammer 40,000: Kill Team
Twin-stick aiming and dodging waves is the action core
Warhammer 40,000: Kill Team leans a little harder on reads, though the gap is small.
Prototype 2
Blackwatch and infected never adapt
Warhammer 40,000: Kill Team
Enemy hordes are scripted, not adapting minds
Warhammer 40,000: Kill Team leans a little harder on variance, though the gap is small.
Prototype 2
Sandbox encounters carry slight randomness
Warhammer 40,000: Kill Team
Enemy spawns and drops add bounded randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Prototype 2
Mutation upgrades and target-hunting routes reward planning
Warhammer 40,000: Kill Team
Class abilities and upgrade paths 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.
