head to head
Zombie Army Trilogy asks more than Manhunt, and the gap is execution.

Optimization · Practiced Mastery
Grim stealth horror about luring scripted hunters into executions.

Execution · Practiced Mastery
A co-op horde shooter testing sniper aim and chokepoint planning against scripted waves.
Manhunt leans Optimization (Practiced Mastery); Zombie Army Trilogy leans Execution (Practiced Mastery).
Zombie Army Trilogy leans clearly harder on execution.
Manhunt
Stealth timing on executions
Zombie Army Trilogy
Long-range sniping and horde kiting demand steady aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Manhunt
Hunters patrol on scripts
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.
Manhunt
Patrol noise reactions add small unpredictability
Zombie Army Trilogy
Spawn timing varies a little between runs
Manhunt leans a little harder on optimization, though the gap is small.
Manhunt
Shadow routes and lure tactics are learnable
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.
