Our take on Slug's Sister Defense

Its defining structure is a central-defense setup: Snail remains in the middle while Slug places automatically firing weapons around her and confronts enemies approaching from every direction.

What is Slug's Sister Defense?

Protect Snail at the center of the battlefield while enemies approach from every direction and try to break her shield.

Slug cannot be hurt, allowing direct attacks against the invading creatures. Equipped weapons fire automatically, while level-ups provide opportunities to obtain and improve weapons and gear. Acquired equipment can be positioned around the battlefield and collected when needed. Some weapons evolve after reaching maximum level and meeting specific gear requirements. Monsters with special abilities add further threats, including enemies that target Slug directly. Battles also provide coins, which can improve gear from the title-menu upgrade screen. These upgrades remain active until reset, allowing either ongoing progression or a reset-based challenge.
