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
Strategic dismemberment under resource pressure, solved by upgrade planning and practiced limb-aiming.

Execution · Practiced Mastery
Planning a clean route through each level, then executing it without a single mistake.
Dead Space (2008) leans Execution (Practiced Mastery); Deadbolt 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.
Dead Space (2008)
Precise limb-targeting under Necromorph pressure is the core skill
Deadbolt
One-hit deaths demand precise shots and clean movement
Dead Space (2008) leans a little harder on reads, though the gap is small.
Dead Space (2008)
Necromorphs follow fixed approach patterns, not player modelling
Deadbolt
Undead follow patrol scripts, never modelling the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Store stock is deterministic; minor drop variance on kills
Deadbolt
Enemy placements are mostly fixed with minor behavioural noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Weapon upgrading, power-node routing and stasis timing are optimisable
Deadbolt
Planning entry routes and kill order is half the level
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.
