Before Twinsen's Odyssey and long before Alone in the Dark, Contraption Zack is among the first games that successfully combined physical puzzles, action, and adventure elements into a fine game. Your job is to help Zack the clueless mechanic pass various levels by using his tools to fix things and pass nasty traps. The game is somewhat reminiscent of Epyx classic Chip's Challenge, but played in a more attractive isometric board, with more parts and items to manipulate.
Zack was one of the most original puzzle/adventure games to come along in the 90s. The game spawned a spiritual successor, D/Generation, the following year, which uses the same engine but focuses more on action and adventure elements.
