Colossal Cave Adventure, the 1995 430-point version.

This is the last descendent of the original 1976 Colossal Cave Adventure worked on by the original authors - Crowther & Woods. It has sometimes been known as Adventure 2.5. The original PDP-10 name 'advent' is used for the built program to avoid collision with the BSD Games version.
