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
Co-op horde defense balancing ballistic marksmanship with chokepoint planning.

Execution · Practiced Mastery
Patient ballistic aiming wrapped in plannable stealth positioning.
Sniper Elite: Nazi Zombie Army leans Execution (Practiced Mastery); Sniper Elite V2 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.
Sniper Elite: Nazi Zombie Army
Long-range ballistic shots and horde kiting demand steady aim
Sniper Elite V2
Ballistics-compensated long shots demand steady precise aim
Sniper Elite V2 leans a little harder on reads, though the gap is small.
Sniper Elite: Nazi Zombie Army
Zombie waves charge on scripted triggers
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.
Sniper Elite: Nazi Zombie Army
Spawn composition varies slightly between runs
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.
Sniper Elite: Nazi Zombie Army
Chokepoint setups, trap placement and ammo economy carry co-op runs
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.
