Cave monsters are after the kingdom's old treasure house, the VAULT! Line up your tiny voxel heroes and keep it safe in this 3D tower defense game. ■ Where you build is where they walk • Units block enemies, so bend the path and send monsters the long way around • The path can never be fully blocked, so experiment freely • Dots on the ground show the current route • Plan routes with 1-gold fences (WALL), then swap in units later • Drop a unit onto an enemy to push it to the next tile ■ A squad that's fun to watch • SWORD: swordsmen leave their posts to rush enemies and slash several at once • ARROW: archers shoot up to 6 tiles away and hop back when enemies close in • MAGIC: mages step forward to cast slowing spells • CLERIC: clerics walk to wounded allies and heal them with prayer • CANNON: gunner-manned cannons blast everything near the impact Swordsmen, archers, mages, and clerics have HP. If they fall, they get back up after a while. ■ Class change at Lv2: 16 classes Tap to upgrade your five fighting units up to Lv4 for new looks, flashier attacks, and fancier posts. At Lv2, choose a class: NINJA dashes around with clones, SNIPER fires 2.8× shots, THUNDER chains lightning from enemy to enemy, ORACLE speeds up allies' attacks, MISSILE downs flyers with homing missiles, and more. Where each class goes shapes your defense! ■ Tricky enemies • Flyers ignore the path and zigzag. Hit them with archers, mages, clerics, or FLAK and MISSILE cannons • Some stop to attack your units; others shoot faraway units on the move • Some split when defeated; others take detours along the way 30 enemy types and 8 bosses. Scouts warn you 2 rounds before each boss arrives. ■ How long can you last? Start with 10 LIFE. Enemies reaching the VAULT cost LIFE; beating a boss restores 5 (max 20). Let a boss in, and it's game over. Rounds are endless, so push past ROUND 100! ■ Play more, grow stronger • Clear 67 challenges to earn points for unit PERKS like power, fire rate, and range. Reassign anytime • Earn your first point at ROUND 3 and start upgrading from your first run • COLLECTION: enemies and bosses you've defeated, with HP, speed, and when they appear • CLASSES: meet every class and watch it battle on a mini board ■ Review every run See damage, DPS, and kills by unit type, plus your MVP. Tap "View on Map" for each unit's stats. ■ Play at your own pace • Game speed: ×½, ×1, ×2, or ×3 • Days pass from morning to night. After dark, enemies glow and fence torches light up (or keep it daytime) • Every 5 rounds, a sweet message arrives, like a letter from the king or gifts from the village ■ In a pinch? Fire NOVA! Defeat enemies to charge ENERGY. When it's full, watch a rewarded ad to unleash NOVA: huge damage to every enemy on the board, bosses included! * No in-app purchases. The only ads are optional rewarded ads for firing NOVA. * v1.x records (kills, challenges, PERKS, etc.) carry over automatically on first launch. * iPhone only, played in portrait. ## Is RETROVAULT safe?
