GURPSよろず

see p. B53
Beings with eyestalks or extra eyes might be able to follow more than one target at a time --as might those with “inner sight” (espers, martial-arts masters, etc.) and robots with advanced sensor arrays.
■代案
「多目標追尾」 has no effect on arc of vision --it just makes it possible to track multiple targets within that arc. 「広視界」 (p. B74) and 「全周視覚」 (p. 39) do improve arc of vision, and often accompany 「多目標追尾」.
■追加特別増強
Multiple Lock-Ons: You can track multiple targets even if you have only one weapon, and gain the benefit of your Aim or Evaluate maneuver if you attack any of them. Use this to represent high-tech sensors and the situational awareness of cinematic warriors. +20%.
■パワーアップ
Like any vision ability, 「多目標追尾」 is suitable for Light power. It also fits a wide variety of supernatural powers --notably ESP and chi powers.
才能 adds to any Sense roll required to keep track of targets.
