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

Execution · Pure Mechanics
Pure arcade twitch survival against memorisable enemy wave patterns.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Commando leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Commando leans clearly harder on execution.
Commando
Dodging bullet streams while shooting is pure twitch
Half-Life 2
Gravity gun and shooting demand precision.
Half-Life 2 leans a little harder on reads, though the gap is small.
Commando
Soldiers spawn in fixed scripted patterns
Half-Life 2
Combine AI scripted, non-adaptive.
Commando leans a little harder on variance, though the gap is small.
Commando
Minor spawn timing noise across runs
Half-Life 2
Almost no randomness.
Commando leans a little harder on optimization, though the gap is small.
Commando
Grenade conservation and pattern memorisation aid survival
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.
