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 · Pure Mechanics
A classic arcade run-and-gun shooter with dodge-roll-based combat.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Cabal leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Cabal leans a little harder on execution, though the gap is small.
Cabal
precise dodge-rolling and aiming execution
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.
Cabal
enemies scripted, no real adaptation
Half-Life 2
Combine AI scripted, non-adaptive.
Cabal leans a little harder on variance, though the gap is small.
Cabal
enemy spawn randomness is modest
Half-Life 2
Almost no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cabal
limited strategy beyond memorizing waves
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.
