Battle Dungeon can be accessed through gateways, which teleports users to the Dungeon. For unknown reasons, the gateway is consisted with monsters that appear identical to the ones inhibiting in Planet Novus. Although they might share the same looks, these monsters have different skills and characteristics that a user might see in Planet Novus. Possibly, these phenomenons might have been caused by Ackain Virus.
There is no specific information on how many gateways currently exist, however it is known that more gateways have been appearing lately. This will cause nothing but harm to the three races. Rumors have been spreading between the Confederate, the Alliance, and the Imperial forces, in Planet Novus, that the gateways are being created by someone (or something) who is hostile towards all life forms in the planet. Be aware that the only person that can explore the depths of this problem lies in the hands of the worriers in Planet Novus.
Monsters, that exist in Battle Dungeon, are ‘Brutal’, ‘Lazhuwardian‘, and ‘Lazhuwardian warriors’. These monsters have an incomparably stronger than preexisting monsters that has been seen on Planet Novus. Also these monsters have a tendency to attack in a large group, hence bear in mind that a user can be outnumbered 1:100.
There are three types of Battle Dungeons. First is the normal Battle Dungeon where the user receives missions along with briefings that explain the objectives. Second is the boss fight Battle Dungeon where the user has to eliminate a given target (usually a strong boss). Third is the dark hole Battle Dungeon where the user is given various clues, like puzzles, to solve problems. With new kind of battle systems, users can enjoy a challenging tale of battles.
To go into the Battle Dungeon, the user must acquire the Battle Dungeon Gateway generator. The Gateway generator can be obtained through monster hunting activities. When obtained, the Gateway will automatically appear once the user turns on the generator.
The Gateway can only last for 30 minutes, hence users must haste before it closes again. The mission briefing will appear once the user has infiltrated into the Battle Dungeon.
The result of the missions can be found in briefings, or through the mission process status icon on the right-middle section. The user (and his companions) must act quickly to finish the missions since Battle Dungeon has a time limit. If the mission was not completed within the time limit, there will not be any rewards regardless of the outcome. When the mission has ended, another gateway will appear to teleport the user back to Planet Novus.
