The Temple Mine, also known as the Abandoned Crystal Mine, Bergen Mine, Bergen Temple Mine or Cold Dungeon, is a location in CrossWorlds. It was a mine that was abandoned when a temple of the Ancients was breached, and the temple's defense mechanisms turned the mining robots hostile. It is the second dungeon in the game, after the Rhombus Dungeon, and the first step on the Track of the Ancients. This is where players obtain the Heat element, as well as the Thief's KeyThief's Key, allowing them to open Bronze Chests.

The Temple Mine is unusual among dungeons, as it contains both Botanics and multiple in-dungeon quests. No other dungeon in CrossCode has either of these, excluding Ku'lero Temple in the DLC.

Bergen Mine

Before it was decided to use Operation Trackwalker to find out more about the Ancients, the Temple Mine was actually a mine farmed for its precious resources.

Temple Mine

The Temple Mine is a Dungeon which holds the first element of the Track of the Ancients. From here, a Seeker can obtain Heat.
Originally, the Temple Mine was just a mine farmed by humans in order to acquire the precious ores and crystals inside. However, the System of the Track of the Ancients interrupted the destructive activities of the miners by taking over the robots used to dig tunnels and carry debris through small Fleazers. Because of the vast destruction of the original temple the dungeon now looks like a mix of both, thus the name.

Layout[ | ]

The mine has five floors that are generally progressed through from top to bottom. However, the mine has many loops and dead-end pathways, and progression through it generally involves a lot of backtracking. The path to complete the mine is as follows:

  • On floor GF, complete the east rooms and find the Mine Key.
  • Unlock the west rooms and complete them to unlock the elevator to floor U1.
  • On floor U1, complete the south rooms and find the Mine Key.
  • Unlock the north rooms. Proceed across the Great Chasm, collecting and using a Mine Key on the way, and unlock the elevator to floors U2 and U3.
  • In any order, complete the U2 south rooms, the U3 west rooms and the U3 east rooms, collecting a mine key from each.
  • Unlock the U3 north rooms and defeat the Infected Digmo mid-boss, obtaining the Heat element.
  • With the Heat element, the U2 west rooms are now accessible. Follow the path back to the Great Chasm on U1, cross it and unlock the elevator to floor U4.
  • On U4, complete the east and west rooms, collecting four Mine Keys and destroying the Stone Walls blocking the path north.
  • Enter the U4 north rooms, using all four Mine Keys to progress, and defeat the swarm of Fleazers to obtain the Mine Master Key.
  • Back on floor GF, use the Mine Master Key to unlock the path north to the boss.

Botanics[ | ]

The Temple Mine is unusual in that, along with the DLC dungeon Ku'lero Temple, it's one of the only dungeons to contain Botanics. The Botanics found here, Egg Pots, are themselves unique as they are the only Botanics that can spawn enemies. Certain Egg Pots, although physically identical to normal ones, have a 20% chance of spawning a Fleazer when destroyed. Generally, the Fleazer egg pots are found in areas reached after the mid-boss, with a few exceptions: Frozen Chamber 2 and Infested Chamber have standard Egg Pots to avoid complicating the major battles there, and Overrun Chamber, immediately before the mid-boss, contains a mix of both kinds.

Role in the Plot[ | ]

In CrossWorlds[ | ]

The Temple Mine is the first step for Seekers following the Track of the Ancients. The site was once a temple of the Ancients, but mining activities from Bergen Village resulted in its destruction. However, the Track ultimately fought back, taking over the miners' equipment and ultimately rebuilding the temple inside the mine.

Seekers visit this location to obtain the Heat element and the Blue Ice ShadeBlue Ice Shade, as well as to learn about the god Di'aro. For completing the dungeon, the Trackwalker General also rewards them with a Circuit OverrideCircuit Override.

In CrossCode[ | ]

Lea races against Emilie to complete the Temple Mine. She wins the race if she completes the dungeon in less than 90 minutes. At the end of the dungeon, the two girls reunite and read the lore displays about Di'aro to prepare for the First Scholars entrance quiz.

Secrets and Challenges[ | ]

  • When playing New Game Plus with the Carry Over Elements option, the Infected Digmo can be skipped. If you later return to do the New Metal quest, the Infected Digmo and Smelter Digmo will both be present, requiring them to be fought as a dual boss.
  • A few encounters in this dungeon lend themselves well to late-game grinding exploits. The large number of weak Fleazers in Infested Chamber can be killed repeatedly by changing maps to autosave, quitting and reloading. This process is one of the quickest ways to gain Levels after hitting the level 70 (78 with the DLC) soft-cap, and can also quickly grant large amounts of money with the Trail BoosterTrail Booster active. There is also a Kamikatze in Frozen Shaft 3 that respawns instantly so that it can be used in a puzzle solution; this is the easiest way to grind Metal Gears for the IT CAN'T BE? trophy, and while slower than the aforementioned Fleazer strategy, this behavior of quickly and repeatedly respawning in the same location can be abused with an autoclicker to grind while AFK.
