head to head
Black Widow asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
A twin-stick arcade shooter testing aim and web defense reflexes.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Black Widow leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Black Widow leans clearly harder on execution.
Black Widow
Twin-stick aiming and movement on the web is the core test
Half-Life 2
Gravity gun and shooting demand precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Widow
Bugs follow scripted spawn patterns, not adapting
Half-Life 2
Combine AI scripted, non-adaptive.
Black Widow leans clearly harder on variance.
Black Widow
Bug entry points add mild unpredictability
Half-Life 2
Almost no randomness.
Black Widow leans a little harder on optimization, though the gap is small.
Black Widow
Prioritizing targets and bonus timing raises scores
Half-Life 2
Linear progression with no builds.
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.
