If you've got a device powered by a Nvidia Tegra system-on-a-chip, a solid internet connection, and one US dollar, you're in for some fun. The price on physics-based puzzler Demolition Inc. has dropped from $3.99 to just $0.99. That's a heck of a deal.

In Demolition Inc., you take on the roll of Mike, the alien demolition truck driver. Some pesky human cities are in the way, and you've got a work order that says to knock them down. To accomplish your task you have access to various otherworldly weapons like giant wrecking balls, explosive cows, and earthquake bombs. The game takes full advantage of the Tegra chip in order to simulate the physics of the world in real time.

When I reviewed the game, I was impressed with the visuals, and some of the levels were incredibly fun to play. However, there was too much planning and not enough destruction for my taste. Demolition Inc. is 98MB in size, so make sure your connection is good. This is one of the few games I've come across that make use of the Play Store's built-in additional data download.

Some levels are a little tedious, but there is a lot of content and rampage mode is genuinely fun. A non-Tegra version was supposed to be out last week, but still no sign of it. At $3.99 I would caution against jumping in with both feet, but at $0.99 Demolition Inc. is a no-brainer.
