If good humor and awry game mechanics are for you, this is your game.
That said, on more than a few areas, the game fails. In the epic manner.
Such as the story. It can be easily seen that Sandblast took care in trying to closely mimic the style of pandemic, but their attempt fell just shy of actually working. Another negative aspect of the game is it's graphics which, although vastly superior to Big Willy Unleashed, have a massive amount of careless flaws.
All in all, Path of the Furon provides a somewhat disappointing yet considerably fun and well written implied end to the series.
