head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
An arcade FPS that scores you for killing enemies in the most creative ways possible.

Execution · Practiced Mastery
Brutal São Paulo shooter pairing cinematic weight with punishing gunplay.
Bulletstorm leans Execution (Practiced Mastery); Max Payne 3 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.
Bulletstorm
Leash, kick, and shot timing drive skillshot chains
Max Payne 3
last-man-standing saves demand precise shootdodging
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bulletstorm
Enemies are scripted fodder for your combos
Max Payne 3
campaign scripted; vestigial multiplayer adds little
Bulletstorm leans a little harder on variance, though the gap is small.
Bulletstorm
Arenas and spawns are fixed and learnable
Max Payne 3
set pieces fixed after first encounter
Bulletstorm leans a little harder on optimization, though the gap is small.
Bulletstorm
Maximising skillshot score per arena is a solvable puzzle
Max Payne 3
cover routing and painkiller management
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.
