You can find in the link below the save file for achieving the More Metal than Man achievement "easily"; you still need to beat the final boss, which I cannot say how easy it will be for someone that did not get the experience of the full game. Nevertheless, do the following:
1. Download the save file from here[www.dropbox.com].
2. Unzip the file and copy it:

• Linux: /home/[USERNAME]/.local/share/Steam/steamapps/compatdata/[NUMBER]/pfx/drive_c/users/steamuser/AppData/LocalLow/Steel Mantis/Valfaris/[LONG NUMBER]/
  
• Windows: C:\Users\[USERNAME]\AppData\LocalLow\Steel Mantis\Valfaris\l[LONG NUMBER]

3. Rename the more_metal_than_man.dat file to Valfaris_Slot_#.dat, where you change the # to the number 0,1 or 2.
4. You are ready to go now!
