To stop Ghost Bloons from bypassing your defenses in Bloons Blitz, place detection units in central locations along the track and align your hero active reveal abilities with your high-damage kill zones. Ghost Bloons ignore standard line-of-sight vision, requiring targeted stealth-detection upgrades or active hero skills before primary damage towers can strike them.

Setting Up Detection Coverage

Ghost Bloons move past standard line-of-sight defenses completely undetected. Relying purely on raw damage towers causes stealth waves to push through your perimeter without taking damage.

To build an effective stealth counter:

  • Position units centrally: Place detection-capable towers where their coverage overlaps with primary damage units.
  • Prioritize low-tier reveals: Upgrade multiple low-cost detection units across the map rather than investing heavily in a single expensive tower that can leave blind spots.
  • Establish coverage early: Purchase detection upgrades before mid-wave density spikes so stealth units are stripped of their concealment as soon as they enter range.

Hero Ability Timing for Ghost Waves

Hero abilities act as a key emergency response when Ghost Bloons threaten to overwhelm your passive detection network. Because active reveal skills operate on cooldowns, precise timing determines whether your primary towers clear the wave.

Use these guidelines when triggering hero abilities:

  • Sync with kill zones: Activate reveal skills right as Ghost Bloons enter the firing radius of your highest-DPS towers.
  • Save skills for stealth waves: Avoid spending reveal abilities on standard bloon waves so cooldowns remain ready for incoming stealth segments.
  • Watch wave indicators: Track incoming spawn density on the enemy bar to trigger skills before stealth units slip past your front line.

Balancing Economy and Tower Space

Spending gold on detection reduces the capital available for pure damage upgrades. Maintaining line integrity requires balancing stealth coverage with offensive output and map footprint.

Strategy FocusPriority ActionRisk to Avoid
Gold AllocationInvest in income generators early to offset detection upgrade costsOver-spending on raw damage towers that cannot see target bloons
Map FootprintSpread low-cost detection units across open mapsOver-crowding placement slots on tight maps with redundant reveal units
Tight LayoutsRely on timed hero reveal abilities when tower space is strictly limitedNeglecting raw DPS while attempting to achieve 100% passive detection

If Ghost Bloons are consistently revealed but reach the exit, shift spending back into pure damage upgrades. If high-damage towers remain idle while enemies pass, expand your detection network immediately.
