Nothing to do with Peter Graves and that old Sixties telly series, but the exploits of Agent 4125 in his efforts to defeat the evil Elvin Atombender, who has set himself up in a multi-towered stronghold.
4125 has to leap around platforms, avoid marauding robots and search for numbers that make a code. Once the correct numbers are obtained, 4125 is allowed access to the next tower. Along the way, he has to bust into safes to record a short piece of music. Once all the music is collected, and recorded in the right order. 4125 can finally defeat Atombender once and for all.
As far as the game itself, Impossible Mission II on the Spectrum is pretty good! The main character graphics are all black, but against the bright colourful backgrounds they work very well. The animation of 4125 is really good, and with the objective of playing against the clock, the action really hots up when time is running short.
Impossible Mission was a classic in its own right, and the sequel as a budget title deserves to do equally well. Grab it at the first opportunity.
