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.

Optimization · Practiced Mastery
Hybrid tower-defense testing maze optimization backed by first-person aim.

Execution · Practiced Mastery
Patient positioning and learned ballistics, executed one careful shot at a time.
Sanctum 2 leans Optimization (Practiced Mastery); Sniper Elite 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.
Sanctum 2
Weak-point shooting during waves carries real aim demands
Sniper Elite
Steadying long shots against wind and breathing demands precision
Sniper Elite leans a little harder on reads, though the gap is small.
Sanctum 2
Alien waves path predictably toward the core
Sniper Elite
Enemy patrols follow scripts, not adaptive minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sanctum 2
Wave compositions vary mildly between maps
Sniper Elite
Guard positions are scripted-but-unknown on first pass
Sanctum 2 leans a little harder on optimization, though the gap is small.
Sanctum 2
Maze layouts and tower economics are the solvable heart
Sniper Elite
Ballistics math, positioning and route planning carry each mission
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.
