head to head
Wild Guns Reloaded asks more than Half-Life 2, and the gap is execution.

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

Execution · Pure Mechanics
A gallery shooter testing aim and dodge reflexes against scripted enemy waves.
Half-Life 2 leans Execution (Pure Mechanics); Wild Guns Reloaded leans Execution (Pure Mechanics).
Wild Guns Reloaded leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
Wild Guns Reloaded
Aiming and dodging dense bullet patterns drives every stage
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Combine AI scripted, non-adaptive.
Wild Guns Reloaded
Enemies are scripted, not adapting to you
Wild Guns Reloaded leans clearly harder on variance.
Half-Life 2
Almost no randomness.
Wild Guns Reloaded
Spawn timing adds mild chaos
Wild Guns Reloaded leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Wild Guns Reloaded
Learning patterns and weapon use aids survival
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.
