head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Irem's gorgeous submarine shoot-em-up crawling through drowned warzones.

Execution · Pure Mechanics
A run-and-gun shooter where memorizing enemy patterns and precise dodging carries survival.
In the Hunt leans Execution (Pure Mechanics); Metal Slug 4 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
In the Hunt
Dodging dense fire in a slow submarine
Metal Slug 4
twitch dodging and shooting precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
In the Hunt
Enemy subs and bosses fully scripted
Metal Slug 4
fixed enemy waves, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
In the Hunt
Near-deterministic arcade patterns
Metal Slug 4
minor drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
In the Hunt
Learning stage layouts and safe lanes
Metal Slug 4
memorized patterns and routes solvable
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.
