Looking for a DOS game from the 80s
 

For the past couple of years I have been looking for an old DOS game from the late 80s. I didn't have a sound card at that time, but the game supported audio via the pc speaker.

It's about a prisoner having to escape from a mental hospital. There are at least four floors with a lot of rooms and cells. There are guards patroling in the halls, and there are sometimes screams from the other prisoners.
Initially, iirc, the character was locked up in a cell, and there was a syringe under the bed or in a wastebasket that had to be used on the guard. Some rooms could only be accessed walking on the cornice. I vaguely remember escaping through a window into a trash bin, but didn't manage to go on from there.

I found some old drawings I did of the building, but unfortunately I didn't write down the name of the game. A friend of mine said it was something with "outbreak" or "break out".

Anyone remember the name of that game, or is it too old for todays gamers?

It sounds like Countdown, by Access Software.

I'm not sure since its many years back when I've played this game. However the plot sounds like a Countdown developed by Access Software.

EDIT: Double-post, I'm sorry Aurebesh. :D

Yikes - not even 20 minutes from I asked.

Thanks a lot, and I can get it from Abandonia. :)
