Realistic robots and vehicles often have 「
走査感覚」s: Radar or 「
イメージング・レーダー」 for use in flight, Sonar to navigate underwater, etc.
Supers sometimes have similar abilities, not all of them realistic. 「
超レーダー」 in particular can represent a variety of supernatural and superscience senses.
The GM may invent new 「
走査感覚」s. Most should cost 20 to 25 points. Here are two more from the real world:
Active IR:
Your 「
走査感覚」 uses an infrared (IR) beam. Base range is 200 yards. It can distinguish fine relief as well as the human eye; if someone using ordinary vision could identify details without a die roll, then so can you. Only IR detectors and those with 「
赤外線視覚」 (p. B60) can detect Active IR. You can switch off your beam in order to avoid detection, in which case this ability functions as 「
赤外線視覚」 (but when turned on, it can spot targets that don’t emit heat). Active IR doesn’t work underwater. 20 points.
T-Ray Vision:
Your 「
走査感覚」 uses sub-millimeter-wave radar, bordering on the infrared.
Base range is 200 yards. Like 「
イメージング・レーダー」, T-Ray Vision can spot small objects and determine their shape, and eliminates penalties to spot objects behind light cover.
However, T-Ray Vision is more precise.
It gets +4 to locate concealed weapons, and while it still requires a Sense roll to distinguish fine relief, this roll is also at +4. Only rare, special- purpose sensors can detect TRay Vision. T-Ray Vision doesn’t work underwater. 25 points.
■代替案(Alternatives)
The primary role of a 「
走査感覚」 is to let the user function in the dark. Compare 「
闇視」 (p. 46), 「
域外視覚」 (p. 51), 「
赤外線視覚」 (p. B60), and
暗視 (p. B71), none of which emit detectable radiation. Another alternative is 「
振動感覚」 (p. 86).
Those who can see through walls using ordinary vision, as opposed to with T-rays, X-rays, etc., should take 「
透視」 (p. 66). Remote viewers have 「
超感覚」 (p. 44).
■追加特別増強(New Special Enhancement)s
Bio-Scan:
「
超レーダー」 only. You receive vital signs and biochemical information from anything you scan -- both the target itself and anything living on its surface. This lets you use skills like
生物学 and
診断 from a safe distance. With Penetrating, you can also examine living beings inside inanimate objects (e.g., the passengers of a car). +50%.
No Intercept:
Your 「
走査感覚」 is completely undetectable. This highly unrealistic enhancement mainly suits psis and supers. +50%.
Scanner:
「
超レーダー」 only. You receive detailed information about the composition, energy output, radiation emissions, etc. of anything you scan.
This allows detailed analysis from a distance with scientific skills such as
化学 and
物理学. With Penetrating, you can spot specific systems within a complex machine and analyze them using
エンジニア skill.
Sci-fi sensors typically have both enhancements --and often Bio-Scan, too. +50%.
■パワーアップ(Powering Up)
「
走査感覚」s are perfect for elemental powers: Radar, 「
イメージング・レーダー」, and T-Ray Vision fit Electricity power; Ladar and Active IR suit Light power; and Sonar is logical for Sound/Vibration power. Electrokinesis (usually psionic) could justify any 「
走査感覚」 except Sonar . . . which 「
サイコキネシス」 could explain.
Other supernatural powers are only likely to offer 「
超レーダー」, which is appropriate for ESP and chi, divine, and cosmic powers that grant heightened awareness.
才能 adds to all Sense rolls to use any 「
走査感覚」.
