@Irtaza1 there is a new mining game called "Glean", it is similar to Motherload and says it is inspired by Motherload so it is probably as close as you will get to Motherload 2
For those who are wondering why they haven't gotten the hard badge after upgrading everything to level 5, you need to go to the galaxy map and go to the red planet.
Here are some tips: If you are trying to get more artifacts, always look in glacial planets and with as much depth as possible. If you need lava globs then find some lava and stick a teleporter underneath it then just wait till your inventory is full/health is low and teleport back to the ship and repeat this process till you have enough. Always have at least one teleporter as they are extremely useful and will last until you change planets, and try and place it as deep as possible so you don't need to climb up to reach it.
If you're near the end of the level, there's a cool prize, but you're about to RUN OUT OF TIME!@!@! Don't fear! As long as you're an administrator on your computer (if not, sorry) then you can set your computer clock back an hour, giving you another hour to complete the level xD
