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
Planning a clean route through each level, then executing it without a single mistake.

Execution · Practiced Mastery
Landmark scripted FPS following Gordon Freeman through the Black Mesa disaster.
Deadbolt leans Execution (Practiced Mastery); Half-Life leans Execution (Practiced Mastery).
Deadbolt leans a little harder on execution, though the gap is small.
Deadbolt
One-hit deaths demand precise shots and clean movement
Half-Life
Combat aim and infamous platforming sections
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deadbolt
Undead follow patrol scripts, never modelling the player
Half-Life
Marines flank by script, not by modelling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deadbolt
Enemy placements are mostly fixed with minor behavioural noise
Half-Life
Set pieces surprise only on first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deadbolt
Planning entry routes and kill order is half the level
Half-Life
Resource routing and encounter knowledge for speedruns
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.
