W4sted's brain analysis has taken a lot of energy, so the commander must get the batteries from the wreckage. The crane is done and his trip begins. The crane is difficult to use and it takes the all day. When back to the base in the middle of the night he doesn't feel good and immediately goes to rest.
The next day he start working on a way to connect the batteries to the base. He builds merge-blocks and uses the crane to put the batteries in position. After that he reads the results of the analysis and notices that he got an heavy concussion and a traumatic brain injury from the crash. Later he builds a connection system to recharge that battery of the rover but this force him to remove the turrets on the roof. So with no defense for the night builds doors for the base and studies the defense drone that he built saying that it's really bad and names it ED 1.01. He wants to do a test run but he realizes that the drone can't even fit through the door and begins to grind it.
