How to unlock the Stubborn! achievement in Bridge Constructor - Definitive Guide
Just keep failing the same bridge over and over 25 times.
It might happen naturally on some of the harder bridges, if you can't wait simply fail a bridge ( you must build at least one piece of the bridge - credit to amenazamenor JF ) over and over by pressing RB and letting cars or trucks go across a bridge that will fail.
Credit to TonySki for recommending using the tanker truck (if you have it unlocked) when it goes boom press A to reload.
Rinse and repeat.
Credit to Dwaggienite for pointing out the following: The xbox achievements app DOES NOT track progress to this achievement unlocking - it will stay at 0% until it unlocks.
Although I initially had the wooden piece be metal, I think it was more consistent that way. This was bridge 6 on Eastern Mainlain, I went with tanker and it would spawn over the left piece of my construction, as soon as it breaks it will detonate the tanker. Each reset was less than 2 seconds. I found the wood piece on the left to break faster, but sometimes it wouldn't explode the truck and just send it flying through the air, so probably all steel is faster. And the weight on the right of what I built, doesn't have to look exactly like that, it just has to be heavy
This requires you to fail a bridge 25 times in a single creation session. From the main map the game proceeds by you selecting a bridge to build. Once you get to this bridge building screen, do not go back to the main map screen or it will reset this failure counter.
Simply build an unstable bridge then press to test it. If you build a bridge bad enough it will fall apart before you even try to send vehicles across it. Either way, the bridge falling apart is what counts for this trophy. You can stay on the test screen and just keep sending vehicles across your failed bridge over and over.
Personally, I never even finished the "bridge destruction" sequence. As soon as one part popped off, I went back to editing mode via and tried again. I unlocked this trophy while trying to figure out an advanced tank truck configuration.
The trophy unlocks immediately during your 25th bridge collapse.
This requires you to run a simulation that is destined to fail 25 times. As long as there are bridge pieces on the map when the simulation starts it will count as a fail provided you run the simulation long enough for the bridge to collapse. Simply restart it 25 times and the achievement will unlock.
