The keep needs a defender. Build towers beside winding paths, command Aldric, and stop the enemy before your lives run out. BUILD YOUR OWN DEFENSE Place defenders on open ground across two 3D battlefields. Cover several bends, move your Beacon to boost nearby towers, and sell or replace defenses as the next threat approaches. SIX TOWER FAMILIES Mix rapid Rangers, explosive Mortars, slowing Frost towers, chain-lightning Arcane towers, armor-piercing Ballistas, and poison-firing Venom towers. Upgrade through five tiers and choose a specialization for each defender. TRAIN YOUR HERO Rally Aldric where the battle needs him. Earn experience toward 100 progressively harder levels, then spend gold on Runeblade, Battle training, or Sunfall mastery. Cast Sunfall to damage and slow enemies around your hero. Hero progress and upgrades last for the current run. ENDLESS WAVES AND SOLO BOSSES Adapt to distinct enemy families, including flying creatures, armored attackers, and fast-moving packs. Every fourth wave brings one powerful boss. Play at 1×, 2×, or 4× speed, pause to plan, and control automatic waves from the map menu. LEARN AS YOU PLAY A first-launch walkthrough highlights the controls. Replay it anytime or open the Field Guide for tower roles, abilities, enemy counters, and spending tips. FREE TO PLAY Optional rewarded ads between waves grant 60 gold when completed. Ads never start automatically, and you can play without watching them. Ad availability varies.
