Now it's time to break the rules. A little. This edition of Weekend Download highlights winners of the 2008 Unity Awards, games created using the Unity plug-in that are playable right in your browser window. Technically they're browser games, but since you have to download and install something, they're downloads, too.
Tumbledrop (Mac/Windows, free) - Walking away with the Best Gameplay award, Tumbledrop is a physics-based puzzle game where you hover the cursor over blocks and, when the timer empties, that piece will disappear. Keep the star from tipping into the water and move it to the ground below to win. And come on, don't you just love the little faces those guys make? Especially the star when it starts falling into the water...
Off-Road Velociraptor Safari (Mac/Windows, free) - An arcade-style game where you play a raptor driving a jeep with a spiky ball and chain attached to the rear. Your goal is to chase down other raptors and throw them into a teleporter that sends them to the future. Seriously! We gave this game a full review when it was officially released back in January.
Rasta Monkey (Mac/Windows, free) - Although it didn't win any official prizes, Rasta Monkey was voted one of the favorites on the Unity Forums poll. You play an extraordinarily happy monkey who tumbles from branch to brand collecting bananas. Hold the [spacebar] to gather up momentum and send yourself flying through the air.
Mars Explorer (Mac/Windows, free) - Another game that didn't score an official prize, but I loved it all the same! Mars Explorer is a 3D planetery exploration game that delivers exactly what the name promises. You spawn as a rover on the red planet whose only goal is to ride around looking at the scenery. Play a basic game of laser tag with online opponents, or just sprout wings and fly around taking in the view.
