Kingdom Rush Vengeance TD+: Clockwork Factory Veteran Guide

To earn a 3-star victory on Clockwork Factory on Veteran difficulty in Kingdom Rush Vengeance TD+, anchor your defense at the central lane intersection with melee blockers, position hero Asra directly behind them to strip armor, and deploy anti-air towers early before pivoting into magic and artillery.

Chokepoint Setup and Path Strategy

Clockwork Factory features multiple catwalks where enemies march across separate routes before converging near your core defense and splitting toward the exits. On Veteran difficulty, mechanized dwarven units have higher health pools, heavier physical armor, and faster march speeds.

Focus your tower building around the central intersection where paths converge. Holding enemies at this junction ensures your towers strike multiple enemy groups at once. If you build towers along separated side routes too early, your gold will be stretched thin, leaving individual towers under-leveled and unable to handle concentrated waves.

Wave Progression and Tower Choices

Balance cheap stall units with early anti-air coverage, then scale into magic and area-of-effect damage to defeat heavily armored mechs.

1. Establish frontline blockers: Build basic barracks units where the main paths meet to stall dwarven foot soldiers and light automatons within tower range.
2. Deploy early ranged coverage: Place Shadow Archers or low-cost ranged towers near entry curves to eliminate airborne drones before they bypass your ground chokepoint.
3. Upgrade barracks durability: Increase blocker health and unit counts before buying costly damage upgrades. Stalling units long enough under sustained fire is essential for clearing mid-tier waves.
4. Add armor-piercing magic: Transition to magic towers like the Infernal Mage or Specters Mausoleum adjacent to your barricades. Physical arrow damage drops off significantly against mid-game armored constructs.
5. Scale into artillery: Add artillery near the main junction to wipe out clustered scrap units and escort drones during the final waves, preventing your magic towers from wasting high-damage attacks on weak targets.

Hero Positioning: Maximizing Asra

Asra provides crucial single-target burst and armor-piercing poison damage against mechanical units that shrug off basic physical attacks.

• Anchor behind the frontline: Position Asra immediately behind your central melee blockers. This keeps her safe from direct melee strikes while allowing her to fire continuously into stalled enemy packs.
• Intercept lane leaks: Move Asra manually along catwalks if fast flyers or rogue automatons slip past the main line. Her mobility allows her to quickly burst down isolated threats before returning to the primary chokepoint.
• Target active skills on clusters: Reserve Asra's active skill for high-health mechanical champions or dense clusters pinned by your blockers to clear bottlenecks efficiently.

Managing Late Waves and Boss Units

During the final waves, large clockwork juggernauts arrive alongside fast escorts and aerial swarms. Keep these tactical adjustments in mind:

• Cluster stage powers: Save global spells like Soul Impact for moments when armored elites group up with fast-moving support units at your barricade, rather than firing at single targets.
• Adjust rally flags: When heavy clockwork bosses slam into your front line, pull your barracks rally points slightly backward. This prevents your melee blockers from being wiped out instantly and keeps the enemy stalled within your kill zone.
• Prioritize core abilities: Invest remaining late-game gold into high-impact tower skills, such as armor-shredding debuffs and burst missiles, rather than placing un-upgraded base towers along the outer lanes.
