PopCap has released a demo for its upcoming tower defense title, Plants vs. Zombies. It's available right now. Here. If you have a PC or Mac, go get it.
That's the story basically. The demo appears to be a 30 minute trial of the game, which should give you a good enough idea of what to expect when the game is available tomorrow for a cool $19.99. Destructoid is also giving away some free copies and today's the last day to win it.
If you've played the demo, let us know what you think so far. We've been playing the full version of the game for a few weeks now, and our full Plants vs. Zombies review is coming tomorrow. But I think it's safe to say "we like it"; how much and why you'll have to wait for.
