head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
A gritty African shooter where systemic chaos roughens every firefight.

Execution · Practiced Mastery
An endless-runner shooter testing steering and aim against zombie crowds.
Far Cry 2 leans Execution (Practiced Mastery); Into the Dead 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 2
Gunplay with degrading, jamming weapons
Into the Dead 2
Steering and aiming while auto-running drives survival
Into the Dead 2 leans a little harder on reads, though the gap is small.
Far Cry 2
Mercenary AI is mappable
Into the Dead 2
Zombies shamble on scripts, no prediction
Into the Dead 2 leans a little harder on variance, though the gap is small.
Far Cry 2
Malaria, jams, and fire spread inject chaos
Into the Dead 2
Spawn placement and pickup drops vary each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 2
Loadout and route planning across hostile terrain
Into the Dead 2
Weapon loadout and upgrade choices 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.
