Mission 22 : Build a more efficient mining robot, the XR-2

As your XR-1 robot should have collected enough ores and you know how to make quantities of various alloys, we'll start making a more powerfull mining robot.

As a comparison, the XR-2 is 2 time faster than the XR-1 and will collect 2 time more cubes per mining cycle. Unfortunately, it is also more expensive to make.

Look at this page to see a comparison between mining robots.

Now, make the XR-2 mining robot. This is the page in the manual where you'll find the manufacturing instructions.

You'll have to make several alloys in order to make it. Remember you made all of them in previous missions.

In case you need to rember the composition of an alloy, all informations can be found in the Melting Furnace page in the manual.

Once you made your mining robot, use it in the same way you did with the XR-1. You'll note that the XR-2 is digging deeper.

Collect some amount of materials with your new robot. We advise you to make several of them.

Once done, your missionis over...
