head to head
Halo Infinite asks more than Half-Life 2, and the gap is reads.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
An arena shooter built on precision aim and power-weapon map control.
Half-Life 2 leans Execution (Pure Mechanics); Halo Infinite leans Execution (Pure Mechanics).
Halo Infinite leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
Halo Infinite
Precision aim and strafe duels dominate.
Halo Infinite leans clearly harder on reads.
Half-Life 2
Combine AI scripted, non-adaptive.
Halo Infinite
Adaptive opponents around power weapon timings.
Halo Infinite leans clearly harder on variance.
Half-Life 2
Almost no randomness.
Halo Infinite
Spawn flips and weapon drops add noise.
Halo Infinite leans clearly harder on optimization.
Half-Life 2
Linear progression with no builds.
Halo Infinite
Map control, weapon timers, and team callouts.
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.
