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 third-person shooter built around two mercenaries juggling enemy aggro together.

Execution · Practiced Mastery
Patient ballistic aiming wrapped in plannable stealth positioning.
Army of Two leans Execution (Practiced Mastery); Sniper Elite V2 leans Execution (Practiced Mastery).
Sniper Elite V2 leans a little harder on execution, though the gap is small.
Army of Two
Cover shooting and co-op timing
Sniper Elite V2
Ballistics-compensated long shots demand steady precise aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two
Aggro system is mappable, not adaptive
Sniper Elite V2
Enemy AI runs fixed alert routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two
Scripted setpieces
Sniper Elite V2
Wind and patrol details vary slightly per attempt
Sniper Elite V2 leans a little harder on optimization, though the gap is small.
Army of Two
Weapon upgrades and aggro manipulation
Sniper Elite V2
Positioning, sound masking and route planning are learnable
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.
