Potentially Hazardous

Potentially Hazardous turns a near-earth object tracking network into a fast visual search challenge. Numbered threat beacons scatter across a 5x5 radar grid. Tap them in the required order as quickly as you can: a correct lock extinguishes the beacon and builds your combo, while a wrong tap costs 2 seconds. Clear all 25 beacons before the countdown hits zero to secure the sector. Later sectors raise the stakes: a dense 6x6 grid with 36 beacons, reverse order from 25 down to 1, and an odd-even alternation protocol that jumps between the smallest odd and largest even target. The grid reshuffles every round, so no two scans play the same. Earn coins from fast clears and spend them in the Supply Depot on six field tools: extra time, next-target ping, error shield, countdown freeze, combo amplifier and a full radar sweep. Ratings from C to S reward sharp eyes and a steady hand. FEATURES - Schulte-style speed tapping on 5x5 and 6x6 grids - Ascending, descending and odd-even scan protocols - Combo system with time bonuses and S/A/B/C ratings - Six working supply items stored between sessions - Synthesized retro radar sound effects, zero downloads - Randomized grids for endless replay value
