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 twin-stick looter shooter blending Housemarque arcade reflexes with a loot-grind build layer.

Execution · Practiced Mastery
Open-zone Metro entry trading tunnels for a cross-Russia survival journey.
Alienation leans Execution (Practiced Mastery); Metro Exodus leans Execution (Practiced Mastery).
Alienation leans a little harder on execution, though the gap is small.
Alienation
Twin-stick aim and dodge under heavy swarm pressure.
Metro Exodus
open-zone gunplay and stealth takedowns
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Alien hordes never adapt.
Metro Exodus
human and mutant AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Random loot cores and weapon rolls.
Metro Exodus
weather and patrols add mild uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Build and core-socketing choices scale the endgame.
Metro Exodus
crafting, scavenging, and approach 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.
