UAP/D — UNIDENTIFIED AERIAL PHENOMENA DETECTED You're piloting an unmarked saucer over rural America. Your mission: extract every cow. Their mission: pretend everything is normal. Hover, line up the tractor beam, hold to lock — but stay out of every cone of vision on the map. Federal agents walk the fields. Helicopters circle overhead. Local police patrol the back roads. Get spotted and the threat meter climbs; max it out and your cover is blown. Three UFO archetypes to fly: HORNET (fast, short beam), STARLIGHT (balanced, mid-range), GREYHOUND (slow, long beam, deep reserves). Each handles differently and changes how you approach a level. MECHANICS - Hold BEAM to abduct cows - Hold OVERDRIVE to outrun a chase — but only as long as your reactor lasts - Hold CROP to trace a crop circle. Any agent that walks into a completed circle latches onto it, broadcasts the location, and pulls the whole investigation toward it. Free distraction. ESCALATION Levels add agents, helicopters, watchtowers, and aggressive AI. Witness photographs appear in the corner each time someone spots you — collect too many and the mission ends. Submit your initials to the global leaderboard or skip and try again. No accounts. No tracking. Just you, the cows, and an increasingly hostile rural night.

Alien Attack's advantage is ratings volume (11 vs 1) and iOS requirement (13.0 vs 16.0). On price, update cadence and device support there is nothing between them.
