Similar in format to the Atari VCS games Adventure and Superman, this is the first of its type that I've seen for the Spectrum.
In a nutshell, you move ETX (any resemblance to a well-known film alien is entirely intentional) round different screens, collecting fruit and avoid the mad professor and MI5 agent.
Helped by his friend Ernie, ETX must collect three pieces of his "telephone", phone home and escape. You can choose the level of difficulty and, in certain positions, make use of ETX's special powers.
Speech is effective and must be at the limit of the Spectrum's capabilities. Graphics are excellent and animation superb.
A combination of graphics adventure, maze and chase games makes this an unusual, fascinating and addictive program which must rank among the Spectrum classics. You've wept over the film, read the book, bought the souvenirs - now get the tape!
