Military Transceiver

After defeating the Core Commander, you will encounter a strange, broken military device.
By fixing it and following the requests of the voice beyond the transmission, the story of Apostles of Ambition begins.

Colonel Sonora, and her Royal Railmen are here to carry out the cause of the Empire. It is your choice to side with them, or to oppose them.

Muse set &amp; Instrumental Tunes

By Equipping the rare Muse set, you can now use "Instrumental Tunes". While holding the 5 available musical instruments, you can now play multiple hidden different melodies which can damage enemies, as well as giving powerful buffs and healing to you and your teammates.

A strange voice from the Transceiver

By defeating the Core Commander, players have a rare chance to encounter a strange military device.
A voice beyond the transmission promises rewards like non other...but only if you bring her valuable information of the Underworld.

Turn Table &amp; Music Vinyls

With the help of the voice, players can now craft the Turn Table that can play music whenever a Vinyl is inserted.
Some vinyls are hidden around the world, and will play their corresponding biome melodies.
