I wish all adventure text games were like this. Full of special fx's and sounds, a lot more appealing than the average text game is. Also shooting aliens on text command, is something you don't find everyday on the Speccy gameslist.
The storyline has nothing particularly special, and you can guess the basis of the plot just from the name. Still, it is well arranged and structured which makes it very enjoyable to play.
A good start to anyone wanting to get into text adventures.
