Vampire Night - No Continues - 100,730

This is a 1 credit high scoring clear of Vampire Night / ヴァンパイアナイト, a House of the Dead like game made by WOW Entertainment from 2000.

Vampire Night is a light gun game themed around Vampires, it has great voice acting (Yeh, hoomans), branching paths, and long boss fights.

The game has a dynamic difficulty (rank) system which sways the difficulty of the bosses, by default the bosses would take 3 hits to deplete the red cancel bar, but this goes up to 6 hits, as quickly as the Stage 2 boss, if you haven't lost a life. As I try my best to show in this video, it is still possible to deal with all the bosses at this difficulty, however, the final boss is way too difficult. When trying to do this run, I had on at least 20 occasions where I would get to the final boss and then end my credit, even if I made it to the boss with 5 lives.

The branching paths in Vampire Night are: On Stage 2, the upper route on is activated by saving Caroline when she gets caught, and later when she gets chased, also if you shoot the door, missing the door will skip that part.
On Stage 3, the branch is chosen by the order of statues shot at the start of the stage, at 11:48 the left and right statues take you their respective ways.
And on Stage 4, the branch is made from shooting the enemies after Caroline appears at 21:56, if you take less or longer than 7.5 seconds, the route is then selected.

There doesn't seem to be a way to display the score on arcade mode on the Playstation 2 version (on an arcade you pull the triggers after inserting a coin in the order: P2, P1, P2, P1, P2, P2, P1)
It is possible to display it on Special Mode, so from what I seem to have worked out, scoring is as follows;
Every hit: 10, Projectiles: 0
All enemies: 100, Hitting weak point: 300,
Rescuing villagers: 400, Flamethrower's tanks: 500
Items: 800, Bosses: 1500, Losing a life: -100,
Stage Clear: 2500, Stages 1&6 award 4000,
Life Ups when on maximum lives: 1000
To maximise the score, you would want to weaken every enemy and then finish them off by hitting the weak point, while losing as few lives as possible. The Arcadia record for this game is 114,620, HIM and M.T have scored over 120k.
The end of stage life bonus is awarded if the accuracy+villagers rescued is over a certain amount, it seems to be 150%. There is no life bonus if you are on maximum lives, which the default is 5 lives.
On bosses, they have to make a noise for it to award the 10 points, so if they have loads more health, it doesn't benefit score.
