UFO -A day in the life- — what should I check first in Subjects changing with time and circumstances?

Residents' behavior and circumstances vary by time, changing available passengers and scenes. A place empty during daytime may work in another period, so unsuccessful rooms merit repeated visits at different times. Changing conditions helps prevent omissions.

📋 Progression checklist
Phase Objective Checklist
Early game Understand the system
  • ・Learn the camera, or Cosmoscope
  • ・Understand room layouts and an apartment patrol route
  • ・Reliably photograph easier aliens first
Midgame Search efficiently
  • ・Track photographed and unphotographed aliens
  • ・Note aliens with appearance requirements
  • ・Patrol without wasting limited attempts
Late game Find missed targets
  • ・Work through the unphotographed list
  • ・Target aliens appearing only under particular conditions
  • ・Check ending requirements
⚠️ Troubleshooting

1. You cannot find aliens

Cause: Appearance locations or conditions are unclear

Solution: Patrol room by room and keep a list of photographed and unphotographed targets

2. Photograph opportunities run out

Cause: Too many shots are guesses

Solution: Photograph reliable targets first and reduce wasted shots

3. One particular alien cannot be photographed

Cause: Its appearance requirements are unmet

Solution: Check time-of-day and event-progress conditions before targeting it
