Item description:

Hello guys!
Here's my save on Bridge Constructor Portal !
She's untested, and waiting for your approval !

Repeat a level (of each chapter?) to obtain the trophies linked to the passage of the test cars, and convoys. You should also get the trophies for 1000 and 5000 portal transitions, and 100 vehicles crashes.
Then, to finish, you'll need to make the contextual action trophies.

I hope this save will contribute to your future platin.
