Two schools of thought (used to) define adventure games. One school says, “an adventure game is a story whose conflicts have been translated into puzzles,” while the second believes, “an adventure game is a puzzle described in terms of a story.” The difference is significant.
If you look at “Corruption” through the eyes of the first school, you will see a vastly unfair and agonizingly difficult work of interactive fiction. The game cannot be finished, or even understood, without experience gained through player-character “death.” Much of the behavior required of the player character, like spying on his peers or breaking into his partner’s office, will, initially, seem unmotivated and paranoid until the player gets stuck in a few dead-ends first. What’s more, I can predict, a little smugly, that everyone will discover, just before he thinks he is about reach “Corruption’s” climax, that he neglected to do something or other at the start of the story, and must replay the entire game. For instance, I found out that I should have thoroughly searched the toilet sometime before the 15th move.
If that sounds irritating and tedious, this may not be a game for you. On the other hand, members of the second school of thought will find a mesmerizing, Chinese-puzzle-box of a game. “Corruption” is a giant riddle, and to decipher its meaning, you must play, and replay, each of its parts. Once the player has mapped out the movements of the non-player characters — who are deftly portrayed, and whose characterizations add much to the bitter, cynical atmosphere of this game — he will recognize a web of deceit and betrayal, and be able guide his character to paths that lead to a satisfying ending.
In short, “Corruption” is a well-written, bug-free puzzle fest, and the puzzles are strongly related to an interesting suspense story. Just remember to save early and save often.
