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 Platinum action game about juggling two characters at once with style.

Execution · Practiced Mastery
An open-world revenge tale where a new shapeshifter hunts Alex Mercer through plague-zoned New York.
Astral Chain leans Execution (Practiced Mastery); Prototype 2 leans Execution (Practiced Mastery).
Astral Chain leans a little harder on execution, though the gap is small.
Astral Chain
Dual character-Legion control demands real dexterity.
Prototype 2
Power-swapping combat and traversal demand decent dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Astral Chain
Enemy patterns scripted, not adaptive.
Prototype 2
Blackwatch and infected never adapt
Prototype 2 leans a little harder on variance, though the gap is small.
Astral Chain
Encounters fixed and replayable.
Prototype 2
Sandbox encounters carry slight randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Astral Chain
Legion abilities and combo scoring learnable.
Prototype 2
Mutation upgrades and target-hunting routes 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.
