Bound to Defend is an endless wave defense game that combines roguelite progression with persistent loot. Level up, draft new skills each run, and experiment with different builds while surviving increasingly difficult waves. Earn gear that permanently carry across runs, allowing you to upgrade, merge, and strengthen your character over time. Combat blends automatic attacks with manually activated abilities, runs can be saved and resumed at any time, and a live cross-platform monthly Top 100 leaderboard lets players compete for the highest score.
