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 · Pure Mechanics
Rhythm FPS where every shot must land on the metal soundtrack's beat.

Execution · Pure Mechanics
The sequel adds branching routes and quicker targets to the arcade light-gun formula.
Metal: Hellsinger leans Execution (Pure Mechanics); Virtua Cop 2 leans Execution (Pure Mechanics).
Virtua Cop 2 leans a little harder on execution, though the gap is small.
Metal: Hellsinger
shooting on the beat is the entire skill test
Virtua Cop 2
Faster targets and hostage shots sharpen the aim test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal: Hellsinger
demons follow fixed behavior
Virtua Cop 2
Rail sequences are fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal: Hellsinger
deterministic arenas
Virtua Cop 2
Branch choices aside, runs are identical
Metal: Hellsinger leans a little harder on optimization, though the gap is small.
Metal: Hellsinger
weapon choice and streak management for scores
Virtua Cop 2
Route branches and spawn memorization drive scores
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.
