Acheton

_Acheton_ is a home computer conversion of the mainframe adventure of the
same name. Similar to Zork (which was released on the VAX mainframe not long
before _Acheton’s_ original appearance), it is a fantasy treasure hunt set in
a claustrophobic dungeon. It boasts over 400 rooms and 200 objects, thereby
making it much bigger than _Zork_.

As with many games of this kind the most time is spent by exploring the
environment and solving item-based puzzles. Everything is described solely
with plain text and the player interacts with the game by typing in phrases
which describe his desired action, e.g. “take bottle”. It also features a help
function with graded hints.
