Investigate with your own hands • New tasks in all ten cases, two per case: sort clues by theory, trace a route on the map, mark the minutes on a timeline, lay tracing paper over a chart, work out a locker code, search for a trace by torchlight, place the boats and find where the fuel went. Nobody gives you the answer — you find it. • Turbo is more generous: more hints in every place, and he rests 2 minutes instead of 5. And once you own the season, Turbo never tires: hints without waiting. • In the first place of a case, objects glow sooner, and the things on the office desk are easier to tap. • Small fixes.

A big update to the investigations • Clues are easier to find: every place has a “To examine” list, and what you have found gets a tick. If nothing turns up for a while, the right objects glow softly. • Magnifier: every case has one detail you have to examine yourself. • Obvious objects no longer stay silent: open lockers, jerrycans, screens and even Flint answer with a line and point you where to look. • Hundreds of small fixes: tap areas sit right on the objects, and Turbo’s hints point at what you can see. • iPad: the game now fills the whole screen.

The finale now ends with “To be continued…”. Small clues are easier to tap. Minor fixes and improvements.

Now in French and Spanish too, fully voiced. On the final board the answers no longer always appear in the same order. Small fixes.

A new final board: one question at a time, your answer is checked right away, and the matching notebook clues sit beside it. Pick the proof from a short list. Clearer proof questions. When you solve a case, you go straight on to the next one. A cleaner screen while you play. Small fixes and improvements.
