head to head
Aliens: Colonial Marines asks more than Hong Kong 97, and the gap is optimization.

Execution · Practiced Mastery
A low-ceiling corridor shooter whose broken AI undercuts every skill test.

Execution · Twitch Chaos
A notoriously broken shooter testing nothing but tolerance and basic bullet dodging.
Aliens: Colonial Marines leans Execution (Practiced Mastery); Hong Kong 97 leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Aliens: Colonial Marines
Standard shooter aim against infamously dumb xenomorphs
Hong Kong 97
Dodging bullet spam with one-hit deaths is the only skill present
Aliens: Colonial Marines leans a little harder on reads, though the gap is small.
Aliens: Colonial Marines
Broken AI barely follows its own scripts
Hong Kong 97
Enemies spawn in mindless waves
Hong Kong 97 leans a little harder on variance, though the gap is small.
Aliens: Colonial Marines
Encounters are fixed and trivially learnable
Hong Kong 97
Spawn patterns have slight randomness
Aliens: Colonial Marines leans clearly harder on optimization.
Aliens: Colonial Marines
Loadout choices barely matter against weak opposition
Hong Kong 97
There is almost no system to optimise
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.
