I mapped this maze at 11pm the day the game came out and as a result I might have missed something. If you find something I missed or have another suggestion then in the future I can update the guide to include that.
**Edit** Updated maps to include 7th treasure chest. My map was missing a chest at B8 and Karnettech's map was missing a chest at D4. If you followed one of our maps and didn't get the achievement check those two places.

The maze has a lot of stuff in it, here's a short list of everything you need to know.

• To summarize what the characters say in-game, the maze has 2 rooms that power the mines and contain puzzles, and you can find the boss by following the tire tracks on the floor.
  
• The 2 ladders leading into the puzzle rooms will be blocked by enemies that can make the ladders hard to see.
  
• There are 7 treasure chests scattered throughout the maze. Finding all 7 will give the player an achievement.
  
• There are 5 places to fight enemies, and 4 new enemies in the mines.
  
• Three of the new enemies are bombs like the nuke. The Acid Bomb has a 70% resistance to stun, the Earthquake Bomb has a 70% resistance to freeze, and the Shockwave Bomb has a 70% resistance to stun and freeze making it the most dangerous.
  
• Right before the boss is a 6th fight with a variety of robot enemies.
  
• The boss, Neon Valhalla, heals a large amount of health every turn, in addition to being able to spawn any of the new enemies from the mine. This boss cannot be captured.
