Bound to Defend is an endless wave defense game that blends roguelite progression with persistent loot grinding. Every run starts from level 1. As you survive enemy waves, you'll level up and draft new skills, creating a different build each run.

Unlike a traditional roguelite, the gear you find doesn't disappear when you die. Weapons, armor and other loot are permanently saved, allowing you to upgrade, merge and sell equipment before your next attempt.

Combat is a hybrid of automatic attacks, passive abilities and manually cast skills using Q, W, E, R and T, letting you play actively or with a more relaxed approach. Runs can be saved and continued later, while the live cross-platform monthly leaderboard lets the Top 100 players compete for the highest score after every reset.
