About this game

Endless monsters are closing in.
The front line is collapsing.
Only the sacred altar must be protected!

Altar Guardians: Idle RPG is an idle defense RPG where you deploy heroes, grow your power, and defend the altar from endless waves of enemies.

Start battles with simple controls, upgrade your heroes and abilities, and hold back enemies that grow stronger with every wave.

Combat runs automatically,
but victory depends on your growth and choices.

Which hero will you upgrade first?
Which abilities will you combine?
When will you unleash your full power?

Every decision can change the fate of the altar.
