• Play at multiplayer, not custom solo.
  
• You need a stable internet connection for these achievements. If you lose connection, that session is useless.
  
• Grinding process can be buggy sometimes. So, make your sessions at medium length; more than 15 minutes, maximum an hour.
  
• Finishing the enemy is the safer approach to finish the game.
  
• Having a balanced team can be a good idea; something like Solaria, Jonah, Ironmaw.
  
• Creator of the experience mode says you need to play in a regular map, not a custom map. So, it can be problematic with the map below. Use it at your own risk.
  
• You need to play in power mode to be able to choose this map.
