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.

Optimization · Practiced Mastery
Planning squad approaches to scripted missions where one mistake kills.

Optimization · Practiced Mastery
A tactical police shooter where careful, methodical tactics against randomized threats defines mastery.
Hidden & Dangerous 2 leans Optimization (Practiced Mastery); SWAT 4 leans Optimization (Practiced Mastery).
Hidden & Dangerous 2 leans a little harder on execution, though the gap is small.
Hidden & Dangerous 2
Deliberate aim and stealth movement punish sloppy hands
SWAT 4
precise aim and careful movement required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
German AI follows patrol scripts, not adapting to you
SWAT 4
suspects react but don't truly adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden & Dangerous 2
Patrol routes and enemy positions are unknown first attempt
SWAT 4
suspect placement and behavior randomized
Hidden & Dangerous 2 leans a little harder on optimization, though the gap is small.
Hidden & Dangerous 2
Squad planning, loadouts and approach routing decide missions
SWAT 4
tactics and equipment loadouts solvable
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.
