head to head
SWAT 4 asks more than Army of Two, and the gap is optimization.

Execution · Practiced Mastery
A co-op third-person shooter built around two mercenaries juggling enemy aggro together.

Optimization · Practiced Mastery
A tactical police shooter where careful, methodical tactics against randomized threats defines mastery.
Army of Two leans Execution (Practiced Mastery); SWAT 4 leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two
Cover shooting and co-op timing
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.
Army of Two
Aggro system is mappable, not adaptive
SWAT 4
suspects react but don't truly adapt
SWAT 4 leans a little harder on variance, though the gap is small.
Army of Two
Scripted setpieces
SWAT 4
suspect placement and behavior randomized
SWAT 4 leans clearly harder on optimization.
Army of Two
Weapon upgrades and aggro manipulation
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.
