I'm not entirely sure what to say about all this. On one hand, I'm a massive Monty Python and the Holy Grail fan, on the other, I'm terribly tired of Angry Birds [99ยข] clones. That being said, Monty Python has existed since the late 1960's and has built of a fairly fantastic reputation for amazing parody over the years, so if anyone can put a funny spin on the Angry Birds formula, it would be them. (Hey, I'm cautiously optimistic.)
In the game, you play the role of the French defending their castle, which should be instantly familiar to anyone who has seen the movie. If this doesn't ring a bell, you should seriously Netflix Monty Python and the Holy Grail immediately, or, I suppose you could just read the synopsis on IMDB (although that doesn't seem like much fun). In the game, you'll be able to fend off the daffy English knights (with the "k" pronounced, of course) in 80 different levels. Your ammo consists of six different types of farm animals, and it sounds like you can even upgrade your catapult.
I have no clue whether or not Monty Python's Cow Tossing will be any fun or not when it actually launches, but I'm hopeful. Admittedly, it really does have the odds stacked against it in the fact that it's not only a game based on a movie (which often can be the video game kiss of death) but it's also an Angry Birds knock-off. Hopefully they're able to cram enough Monty Python humor in to the game that it's at least funny to play. I've got my fingers crossed, anyway.
