Werewolves of London is a video game released in 1987 for the ZX Spectrum, Commodore 64 and the Amstrad CPC.
The game is set in London and the plot is to kill each of eight members of an aristocratic family who put a curse on the main character, resulting in his daily transformation into a werewolf.
The player must then track down each of the eight enemy characters and kill, and optionally, eat their bodies, while avoiding being shot or captured by the police.
After the Werewolf transforms back into a human, the player can wait to be released or can break out with a crowbar and escape through the sewers (a torch is needed to see in the dark).
Your Sinclair magazine said it "doesn't work at all – what was envisaged as an atmospheric arcade adventure ... is just an aimless chase-about".
