Necro Defense is an idle 2D pixel-defense game where players summon undead units to defend a castle, customize a necromancer build, and grow stronger even while offline. The game blends light tactical decisions with long-term progression: allocate skills in a unique necromancer tree, equip and upgrade gear to boost your minions, and clear dungeons to farm materials for improvements.
