Threat Assessment

From Wikitroid, the Metroid wiki

The Threat Assessment its a gauge that indicates the enviromental hazards (like Phazon or lava) in Metroid Prime and Metroid Prime 2: Echoes. The Threat Assessment will grow as Samus Aran draws closer to the danger, when the hazard may harm Samus, the bar will beep and sign with the word "Warning". If Samus comes into contact with the hazard, she will receive damage and the bar will sign "Damage".

If Samus uses the Thermal Visor or the X-Ray Visor, numbers will appear beside the bar to inform of the distance from Samus and the harmful substance, with 10.0 being the farthest and 0.0 being the closest (measurement unit unknown).

[edit] Trivia

• The Scan Visor is the only visor without this bar.
• Most substances like magma will cause the bar to rise. But Phazon and Dark Aether's atmosphere show no indication of warning until contact. (Exception is in Metroid Prime 2: Echoes. Phazon does not raise meter)
• On the way to the crashed Frigate Orpheon Samus comes across a crate oozing Phazon and her meter goes up, despite it being phazon.
