Friends and I have spent countless hours playing this game. Once, a foursome of us, across the United States and Europe, played the Horde Mode past Round 5 (that's 21 waves per round so 105 waves). We'd heard that was how to beat the Horde Mode, but when it didn't end we called it a night. The next day, I emailed the game company and learned that Horde Mode goes on forever! Regardless, we had a great time and we still come back and play the game from time to time.
Every aspect of the game is enjoyable, and playable over and over again. The 'campy' nature of it and 'pulp' action is welcoming and addictive. The background graphics are very detailed. The voice actors are phenomenal. The narrator still cracks me up with laughter. I would like to see it preserved because it's very unique. I have yet to find its equal.
