Kingdom Rush Vengeance

Tower defense where you command the villain's army. You're working for Vez'nan, a dark wizard, placing defensive towers to stop waves of heroes trying to thwart his plans. The twist: enemies include former allies from previous campaigns. You'll position units across multiple territories, managing resources to upgrade towers and deploy special troops. Each stage throws different army compositions at your defenses, requiring you to adapt tower placement and troop timing. Success depends on choosing the right mix of tower types for each map's layout and enemy roster. If you've played tower defense from the hero's side, this flips that script.
