Vampire Radar is a battle between vampire and humans, with 8-9 human pawns starting the game on the square grid map. The vampire is invisible, so there's no vampire pawn, but he IS somewhere on the map. The only clues are from radars. When a human uses a radar, the humans get to know how far the vampire is from the radar. With the clue from the radar and guessing his moves, humans shoot their guns blindly, trying to damage the vampire.
Before all bullets are spent or all humans are killed, if the vampire's life is reduced to zero, the humans win. The vampire wins when he kills all the humans or when the humans are out of bullets.
The second edition of Vampire Radar has nine 2x2 tiles instead of 36 1x1 tiles, making for faster set-up, and it includes variant rules for the human players. Instead of each human player taking two actions, then the vampire acting twice, each human player takes one action, then they pass the starting marker clockwise, then each human takes another action, then the vampire acts. This change rotates the turn order among the humans.
ヴァンパイアレーダーは、人間対ヴァンパイアの戦いのゲームです。
格子状のマップに8~9人の人間駒を置いてゲームを始めます。ヴァンパイアは目に見えないので、駒はありませんが、マップ上のどこかにいます。
唯一の手がかりはレーダーです。レーダーを使用すると、ヴァンパイアとの距離がわかります。人間はレーダーの手がかりからヴァンパイアの動きを推測し、虚空に向けて銃を撃ち、見えないヴァンパイアを攻撃します。
弾丸が尽きるか人間が全滅する前に、ヴァンパイアのライフを0にできれば人間の勝利です。
(This game was first published with an English title "Vampire Rader". However, the correct translation of the Japanese name ヴァンパイアレーダー is "Vampire Radar", and the second edition of the game features this title.)
