"Disinfection" – the 5th and last game of a series about a Sewage Treatment Plant. This is a Beta version. We welcome comments and suggestions. Please send any and all to games@terramater.pt

The instructions are written in Portuguese. So here is a brief rundown. Destroy all bacteria before you create a biohazard. You can use either the mouse or the keyboard – right and left arrows to move and the Space Bar to shoot.
