The game comes with the soundtrack, which is by Long Dao and classical composer Walter Eres.
Immortal Defense There is a way to turn the visual options down, but even with all the options turned down, it can still be quite flashy.Immortal Defense has a story-driven campaign with 100 core levels and 50 optional side-quest levels (which can be completed for bonuses that help you with the core levels). If you have sensory issues, such as epilepsy, this game might cause more problems for you than other games. The game also comes with a level editor, with Steam Workshop support, and is pre-packaged with an extra 62 levels created by fans.
