Start merely as a humble helium atom, but slowly evolve into more complex elements in Sub-Atomic War. Use the arrow or WASD keys to move, and fire by clicking the left mouse button. You can switch between the different weapons you have collected by pressing Spacebar. Collect blue electrons to protect yourself, and green neutrons in order to evolve. Although neutrons help you advance in the game, electrons are vital, because without them, you have no way of defending yourself against enemy atoms.
