In a previous mission, we built the slow materializer in order to materialize cubes stored in Atomic Compressor. Now, we'll make the counterpart device, the slow dematerializer in order to store cubes in an atomic compressor.
As we remain at an early stage of the game, we'll continue to make the "slow" affordable version of these devices.
At this stage, you'll have to search in the manual where is the page for the slow materializer with it's manufacturing instructions.
When you have the dematerializer, place it at the side of an atomic compressor. Then, place a blackrock in front of the dematerializer and you'll see it to disappear. You'll find it in the atomic compressor.
Now, your mision is over..
