Tardigrades
Water bears survive boiling, freezing, radiation, and outer space. Your job is to clear them out of one petri dish anyway. They keep multiplying, so spend your DNA on bigger weapons, and save up for the nuke.
Petri dish defense
Stop the water bears
Tap to squish. They split, they wander in, they survive almost anything. Spend DNA on bigger weapons and save up for the nuke.
1000 DNA. Clears the whole dish and ends the round. 1000 DNA to go.
Best: 0 squished. Selected: Squish — A firm boop. The one thing they can't survive.
About half a millimeter long, with eight stubby legs tipped in claws. They live in moss, lichen, and leaf litter nearly everywhere on Earth.
Dried out, they curl into a barrel called a tun and nearly stop their metabolism. That's why curled-up bears in the game shrug off heat, cold, salt, radiation, and vacuum.
In 2007 tardigrades rode outside a satellite, exposed to the vacuum of space, and some came home alive. They also take thousands of times the radiation dose that kills a person.
Real tardigrades don't split in two; they lay eggs. And squishing really does work.
