This is the Difficulty Pack for Dwarfs!? If you are REAL Dwarfs-lover, then the Easy and Normal difficulty levels in the Arcade mode just won't be enough for you. You will need more difficulty! So, this add-on is for you - it adds in the following extra difficulty levels (the 5, 15, 30 and 60 minute versions) for you to play in Arcade mode:

• Hardcore - more enemies, they move faster - and so does the lava!
  
• Tedi Hardcore - named for the coder half of Power of 2. Hardcore wasn't hard enough for him, so he made it EVEN more difficult!

And remember - the core game is always FREE! You buy the add-on packs once and can play them with no restrictions, for ever after!
