Mission Briefing
Your budget is
under attack.
Ad fraud, click bots, and budget-burning threats are swarming your campaign. Place strategic defenses before each wave and hold the line.
01 / Prepare
Place Your Towers
Spend your starting budget on 6 tower types — from the Retargeting Pixel to the Influencer Collab. Click any open tile to deploy. Towers can't block the enemy path, and you can sell any for $50 to reposition.
02 / Defend
Survive the Wave
Hit "Launch Wave" to send the assault. Ad Bots, Blockers, Click Fraud, VPN Bypasses and Budget Whales march your path. Towers fire automatically — each kill earns budget back. Don't let anything leak.
03 / Optimize
Upgrade & Maximize ROAS
After each wave, choose one power-up: boost damage, speed, range, income, or inject emergency budget. Survive all 10 waves with budget intact. Your ROAS — kills vs. spend — determines your rank.

SWARM
Your Arsenal
Build your
defense stack.
Six ad towers, each with unique stats. Balance damage, range, slow effects, splash radius, and income generation to build the optimal defence stack.
Retargeting Pixel
Precision Strike
High damage, long range. Locks onto the highest-threat target in range. Your go-to for eliminating elites and boss units before they drain the budget.
$200
Email Sequence
Slowing Fire
Moderate damage with a slow debuff — tagged enemies move at 48% speed. Best placed early in the path to give other towers more shots.
$150
A/B Test
Splash Damage
High damage with area-of-effect splash. Expensive but devastating against packed formations. Essential for clearing swarm waves of Click Fraud.
$350
Conversion Funnel
Income Engine
Low damage but earns +$10 per kill — the only tower that compounds your budget over time. Place early to maximise income across the run.
$500
Lookalike Audience
Long Range Sniper
Extreme range at 4.2 tiles and the highest single-target damage output. Covers the entire map from a single placement. Late-game essential.
$450
Influencer Collab
Power Tower
Maximum damage, splash radius, and +$20 per kill. The most powerful tower in the arsenal. Save up for at least one — it solo-carries Budget Whale waves.

FAQ
Common
questions.
How do I place towers?
Select a tower card from the sidebar, then click any open tile on the map. Towers can't be placed on the enemy path. You can sell any tower for $50 using the Sell button.
What happens when budget hits zero?
Game over. Every enemy that reaches the exit drains your ad budget — Ad Bots cost $300, Budget Whales cost $1,000. Don't let anything leak.
How do upgrades work?
After each wave you pick one power-up: Creative Refresh (+20% damage), Real-Time Bidding (+20% speed), Audience Expansion (+15% range), Revenue Attribution (+15% income), VC Funding ($1,500 injection), or Media Buy Refund (recover 10% leaked budget).
What does ROAS represent here?
Return on Ad Spend — budget earned from kills divided by budget spent on towers. Higher ROAS means a leaner, more efficient campaign. It's the primary ranking metric on the leaderboard.
How do I beat the Budget Whale?
The Budget Whale has 600HP and leaks $1,000 if it escapes. Stack Lookalike Audience and Influencer Collab towers near the centre of the path. The Influencer Collab's splash + $20 per kill makes it the most efficient answer.
Is there a strategy guide?
Open with a Retargeting Pixel + Email Sequence combo. Email Sequence slows enemies so the Pixel gets more shots. Rush a Conversion Funnel by wave 3 for income. Save up for Influencer Collab before the Boss wave hits.
