You need to ignore the shonky premise of you how are are at the scenes of these procedural emergencies across continents and decades, as the actual meat of your investigations are strangely satisfying.
In a series of vehicular accidents, your job is not to be a hero but to apply perception, prioritisation and stringent logic to how you will both try to help the victims and then work out what happened. Make the area safe, prioritise who you can save and act quickly and then, when you're relieved by the emergency services follow the clues to find out what was occurin'
There's little freedom here, to succeed you have to follow a strict set of instructions which are drilled into you early on but that is kind of comforting as you accept your roleplay combo of a first-at-the-scene / first aid and safety expert / insurance investigator. Bet you never read THAT sentence before!
Each accident plays out with a similar set of priorities, although they do occasionally get changed up with curveballs here and there, and the need to do things quickly but safely can be challenging, but is relieved by a very effective time-rewind option.
I really liked playing this although, as many other have said, it feels too short by, like, a half. Yet despite the procedures, each are unique and fulfilling while being a bit different to most games. It's biggest single frustration is no achievements. I know not everyone cares, but this game was absolutely crying out for achievements and it's a shame it isn't enhanced in that way.
But let's be honest here, you didn't buy it for the achievements. You bought it for the simulated recreation of the accident you just solved at the end of completing each investigation, Seconds From Disaster style, which are achievements in themselves. You sicko!
