Atomic Defense

A tower defense game that happens inside a single living cell.

Early internal testing on Android

An atom tower fires blue beams at red viruses above a glowing cell.

You are the immune system. Waves of viruses, bacteria and other microbes push in toward the cell, and your job is to hold the line.

Here is the part that makes it different. Your towers are atoms. On their own they get the job done, but the real power shows up when you bond them together into molecules. Pick the right two atoms, snap them into a bond, and you get a brand new defender with its own attack.

The game is in early testing right now. It is free, there are no ads, and it does not collect any of your data.

Highlights

  • Towers are atoms. Alkali metals, noble gases, halogens, transition metals, the carbon group and radioactives, each with its own attack.
  • Bond them into molecules. Snap two atoms into a bond and get a brand new defender. There are a lot of recipes to find.
  • Defend a living cell. Viruses, bacteria and other microbes come in waves along the cell's paths. Work out which combination gets you through a nasty wave.
