Building comparison
head to head
Metal SlugvsU.N. Squadron
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.
Metal Slug
Execution · Practiced Mastery
Twitch dodging and shooting layered over memorised arcade stage routes.
U.N. Squadron
Execution · Practiced Mastery
A Capcom side-scrolling shoot-em-up with a shop economy between missions.
Metal Slug leans Execution (Practiced Mastery); U.N. Squadron leans Execution (Practiced Mastery).
Metal SlugU.N. Squadron
Axis by axis
Execution8 vs 8
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug
Dodging dense bullet patterns and precise shots carry every credit
U.N. Squadron
Dodging dense fire and boss patterns is the test
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug
Enemies follow fixed arcade scripts, never adapt
U.N. Squadron
Enemy waves are fully scripted
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug
Spawns are nearly deterministic once a stage is learned
U.N. Squadron
Deterministic stages once memorized
Optimization6 vs 6
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug
One-credit clears come from memorising routes and spawn patterns
U.N. Squadron
Shop purchases, pilot choice, and pattern routes
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.
