About I Have No Mouth and I Must Scream

This game is specifically packaged for Ubuntu/SteamOS for download from the Steam page.

Note: Steam lists a 486 cpu as a minimum requirement despite the fact it is extremely unlikely the average user could successfully run Ubuntu or Kubuntu on such a machine (not sure about the Ubuntu based SteamOS, which might be pre-configured for pre-pentium compatibility?). An ordinary Ubuntu CD 10.10 (Maverick) or later version will not install on a 486 machine and special methods to do so are required (the problem is actually the Linux kernel version used). In fact, the version of the game is specifically packaged for Linux and has two recommended custom engines to choose from. One is heavily based on DOSbox source code, the other on SCUMMVM source. There is also nothing to prevent the player from using their own DOSBox, SCUMMVM, real DOS, virtual machine with real DOS, or other DOS emulator or DOS clone (the publisher made specific modifications in packaging to allow for these).

GOG provides a DOSBox installer package or as a tar.gz (for those who wish to bypass GOG's installer and redundant DOSBox installation)
