Scanner fails before threat appears

Walters' scanner equipment flickers and dies just as the first signs of the awakened alien threat become visible on the horizon. His sudden loss of critical technology coincides with the team’s realization that their equipment may have been compromised by the alien’s awareness or infiltrated by something more sinister. The malfunction strips the group of their technological advantage at the precise moment the danger they have been warned about begins to manifest, plunging them into crisis before the true enemy is even in sight.
