Your system is under attack.

Every upgrade you take makes the bugs stronger.

Zero Bugs Given is a roguelite tower defense set inside a digital ecosystem under siege. Build defenses on a procedurally generated hexagonal grid. Fight back wave after wave. And face the real challenge — every time you grow stronger, so does the threat.

EVERY POWER HAS A PRICE

After each wave, you pick one of three upgrades. Each one makes you stronger — but also makes the threat worse.

Boost your damage? Enemies get tougher.
Increase your income? The next wave hits harder.
Play it safe? You'll never scale fast enough.

The Bonus/Malus system is the beating heart of Zero Bugs Given. A constant tug-of-war between greed and survival. No two runs feel the same — because no two players make the same mistakes.

THE GRID FIGHTS BACK

Your battlefield isn't just terrain. It's a ticking bomb.

As threats fall, the ground beneath them corrupts — turning tiles into hostile zones that heal, accelerate, and even duplicate anything passing through. That perfect chokepoint? It's now a death trap. For you.

Tower defense isn't just about where you build. It's about where things die.

A MAP THAT BREATHES

Every session starts small. New rings of hexagonal terrain unlock as you progress — revealing paths you didn't plan for and chokepoints you'll need to exploit. The battlefield expands. The pressure never stops.

TWO WAYS TO PLAY

Campaign — Defend 5 Outposts across a growing hex grid. When one falls, sacrifice it to restore Integrity — trading territory for survival. Survive 30 waves. Then do it again in New Game+, where the system starts broken.

Classic — One goal. No safety net. Pure tower defense.
