Bacteria

You are a white blood cell circling inside a big cell. Bacteria are born at its centre and wander, and one that reaches the membrane infects the cell and costs a unit of health. Shoot them, the shot flying through the centre to the far wall, or ram them for more points. A virus creeps slowly round your orbit; touching it costs health and sends you back to the bottom and the virus to the top. The clock bar fills, and when it is full the round ends and the next has one more bacterium, from one up to five. After round five comes the next level, with one bacterium again, everything faster and health restored. After 24 infections or stings you have failed the mission.

Controls: Use either controller. Left and right move round the orbit and a button fires. On the title, up and down choose and a button starts.
