Damian Walker 3 Barbarians is a game of strategy for one player, running on Psion handheld computers. You take the lead of a civilised league of twelve cities at the very time the barbarians are entering the land. Your task is to raise armies and send them against the advancing hordes, and you will not rest until every last one is wiped out. While this is going on, you have to manage your empire's economy. Click here for the manual for all versions of the game, or here for Damian's website.

Barbarians will run on the Psion Series 3 (128K or 256K), as well as other 16-bit EPOC machines that can emulate a Series 3. That includes the Series 3a, 3c, 3mx, the Siena and even the industrial Workabout computers. The game files take up about 32K of space on SSD or in internal memory, and the game takes another 32K of internal memory when it is running. Each saved game is about ½K.
Damian Walker 3a, 3c, 3mx, Siena, Workabout The same as above, but runs on the Psion Series 3a, 3c, 3mx, Siena and Workabout, including models with just 256K of memory. The game files take up a maximum of 180K on an SSD or in internal memory, though this can be reduced to under 40K by removing sound and unnecessary graphics files. When running, the game takes an additional 70K of internal memory. On a 256K Series 3a it is therefore recommended to use an SSD if available, or to do without sound if not. Saved game files are about ½K each and are compatible with the Series 3 version.
