Welcome to Subeta!

If you look at the Battle forums, there are a lot of advise you can read up on.

The equivalent we have for the Hidden Tower is probably is the Millionaire Center - that is located in Centropolis, but it is not a secret shop. There is also an Antique Shop under Commerce > Special Shops on the top nav bar, where old plot items can get re-released.

There are wars with plot events and things like that, as well as secret challengers which can be unlocked, and a lot of info for that is on the Battle forums. There is also a Battle Chat thread where users can help guide you :)

Our battle system also has loot drops, which is enjoyable for a lot of battlers. If you have any other questions don't be a stranger :)
