To play Valhalla upon its release back in 1983, the gamer had to spend a whopping £14.99 for the privilege. For most people this amounted to many weeks of accumulated pocket money, and suggested the game must be something extra special to warrant such a price.
The game is a graphical adventure written primarily in the Spectrum's native BASIC programming language with a little machine code thrown in for good measure. The top part of the screen depicts the player's location in colourful, detailed graphics whilst underneath a textual account of the action provides a communication interface between the player and the game.
The game's text parser is clever, understanding complex sentences and astutely identifying any (more traditional) swear words. Typing in an unfavourable word or phrase sees a dwarf enter the graphical scene and punch the player's character, obviously the most appropriate punishment for such insolent, rude behaviour. The adolescent player, of course, often had more fun testing the games "offensive" word list than playing the actual game.
