There was a download of Pestis 4.5 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. We recommend checking the downloaded files with any free antivirus. The software lies within Games, more precisely Arcade. This free software is a product of Falco Software Company.
From the developer:
Middle ages. A young Plague Doctor who has just studied at the Academy is sent to a small village, which, like the whole country, is covered by the plague. He will remember all his lessons and try to save as many people as possible and, at the same time, not to get infected himself.
You may want to check out more software, such as Battleracer, Pacz or Acky's XP Breakout, which might be similar to Pestis.
