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.

Execution · Practiced Mastery
A squad shooter about leading a resistance through occupied New York, balancing gunplay with simple squad orders.

Execution · Practiced Mastery
A co-op horde shooter testing sniper aim and chokepoint planning against scripted waves.
Freedom Fighters leans Execution (Practiced Mastery); Zombie Army Trilogy leans Execution (Practiced Mastery).
Zombie Army Trilogy leans a little harder on execution, though the gap is small.
Freedom Fighters
Third-person gunplay and squad command under fire
Zombie Army Trilogy
Long-range sniping and horde kiting demand steady aim
Freedom Fighters leans a little harder on reads, though the gap is small.
Freedom Fighters
Soviet AI is scripted, not adaptive
Zombie Army Trilogy
Undead waves follow predictable spawn scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Freedom Fighters
Minor encounter variation
Zombie Army Trilogy
Spawn timing varies a little between runs
Freedom Fighters leans a little harder on optimization, though the gap is small.
Freedom Fighters
Charisma economy and mission order across the map
Zombie Army Trilogy
Choke points, trap placement and ammo economy reward planning
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.
