head to head
Danmaku Unlimited 3 asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
A bullet-hell shooter testing precision dodging and scoring through scripted patterns.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Danmaku Unlimited 3 leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Danmaku Unlimited 3 leans clearly harder on execution.
Danmaku Unlimited 3
Precise dodging through dense bullet patterns is everything
Half-Life 2
Gravity gun and shooting demand precision.
Half-Life 2 leans a little harder on reads, though the gap is small.
Danmaku Unlimited 3
Bosses fire scripted patterns, not adaptive
Half-Life 2
Combine AI scripted, non-adaptive.
Danmaku Unlimited 3 leans a little harder on variance, though the gap is small.
Danmaku Unlimited 3
Minor item randomness, patterns deterministic
Half-Life 2
Almost no randomness.
Danmaku Unlimited 3 leans clearly harder on optimization.
Danmaku Unlimited 3
Scoring systems and ship choice optimize underneath
Half-Life 2
Linear progression with no builds.
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.
