Something is wrong in the tool factory… the alarm sounds that gives us the warning of failure in the machinery systems, a conveyor belt has broken, and the belt has gone crazy. There are tools that are falling to the ground and breaking.

We have received a call from the Chief that has startled us. He wants us to go to the factory urgently and drive two heavy but very slow trucks to get the tools and avoid damage.

We'll be paid £10 per tool recovered, with a bonus if we take more than 50. But if we drop more than 10, we won't fill the bag and lose our job.

A game of skill and visual agility that will make us have a good time sitting in front of our PCW.
