A walkthrough of the ZX Spectrum game, Hyperaction. A 1984 maze game from Silversoft. The cassette had a different version of the game on each side, and both are shown in this video. The second version starts at 07:08. Both versions are completed until they loop around.
From the recording originally sent by Keith Rundle to http://www.rzxarchive.co.uk/ . Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get into difficulty, and try again.
