Petri Defence

Place clever cells, stop every germ. Quick Relaxed levels, a new Daily every day, and a rebuilt Hardcore: four chapters, four bosses, one life.

Germs are heading for the heart. Place your cells, shape their path and stop every last one.

Petri Defence is a small tower defence game that is all about where you put things. Each level is a petri dish, a handful of cells and a stream of germs. Put a T-cell where it matters, aim an Antibody down the path, catch the slow ones in a Net or let an Enzyme fizz them from the inside. Then press Start and watch your plan work. Or not, and try again.

TWO WAYS TO PLAY • Relaxed: endless one-minute levels, three stars to chase and a gift box every few minutes. Easy to pick up, hard to put down. • Hardcore: four chapters of hand-made plates in an engraved anatomy-atlas look, each ending in a boss. One life per try and a par to beat. You will lose. You will learn. Then you will find the answer.

A NEW LEVEL EVERY DAY • The Daily level has its own twist each day. Keep your streak going.

GERMS WITH IDEAS OF THEIR OWN Tough ones, fast ones, shelled ones, germs that split in two, Poppers that stun your cells when they burst, Shields that block your beams and Slimes that skid away. Each one makes you rethink your layout.

FAIR AND FRIENDLY • No energy timers and no waiting. Play as long as you like. • Earn ATP by playing and spend it on hats, pop effects and colours for your cells. Looks only: nothing makes the game easier. • Works offline. Your progress stays on your device.
