Package blurb: The planet Doomawangara (*Doom for short*) is a dangerous place. As the only explorer ever to survive it (*'Countdown to Doom'*) you should know! However, an unexpected distress call sends you flying back to Doom in a mission to rescue an ambassador who has been kidnapped by renegade robots. After surviving a deceptively simple beginning, you'll meet lots of original 'Killworth' puzzles: alternative universes, weird weather; an empty field will never look the same again! You'll acquire a talkative four-legged friend, who'll make you feel like laughing one minute, and crying the next - maybe even both at the same time! The game ends with a danger-a-minute sequence that would even scare Indiana Jones (half) to death. Game size: "large" and Difficulty level: "advanced."
