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 retro-Soviet action shooter mixing gunplay with light upgrade strategy.

Execution · Practiced Mastery
Arcade flight and shooting precision over fixed missions with learnable score routes.
Atomic Heart leans Execution (Practiced Mastery); Star Fox: Assault leans Execution (Practiced Mastery).
Star Fox: Assault leans a little harder on execution, though the gap is small.
Atomic Heart
Shooting and dodging carry the combat.
Star Fox: Assault
Arwing dogfights and on-foot aim demand steady twitch play
Star Fox: Assault leans a little harder on reads, though the gap is small.
Atomic Heart
Robot enemies follow scripted patterns.
Star Fox: Assault
Versus mode adds light human prediction; campaign is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Atomic Heart
Encounters largely fixed.
Star Fox: Assault
Missions play out identically each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Atomic Heart
Upgrades and weapon crafting learnable.
Star Fox: Assault
Scoring routes and boss patterns are learnable
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.
