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
Frozen-planet shooter about managing heat while gunning down giant bugs.

Execution · Practiced Mastery
An open-world revenge tale where a new shapeshifter hunts Alex Mercer through plague-zoned New York.
Lost Planet: Extreme Condition leans Execution (Practiced Mastery); Prototype 2 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.
Lost Planet: Extreme Condition
Grapple movement and Akrid weak-point shooting
Prototype 2
Power-swapping combat and traversal demand decent dexterity
Lost Planet: Extreme Condition leans a little harder on reads, though the gap is small.
Lost Planet: Extreme Condition
Multiplayer modes add some mind games
Prototype 2
Blackwatch and infected never adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet: Extreme Condition
Campaign encounters are fixed
Prototype 2
Sandbox encounters carry slight randomness
Prototype 2 leans a little harder on optimization, though the gap is small.
Lost Planet: Extreme Condition
Thermal energy management and boss weak points
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.
