Carmageddon free, The Incident and more on sale

Just in time for the weekend, here's a few apps that have dropped their (already cheap) prices even lower, meaning that you've got plenty to play here for just a few bucks' worth (all prices USD).

• The PC classic turned iOS port Carmageddon has gone completely free for today only.

• The Incident is on sale for 99 cents.

• The Sky Gamblers: Storm Raiders flight-simulation title has dropped down to just a buck.

• Just a few weeks after release, Sega's dropped The House of the Dead: Overkill to just $2.99. The game's not fantastic, but it does have a really innovative shooting mechanic built for iOS.

• Crazy Taxi is also on sale for 99 cents.

• Zach Gage's Halcyon is currently completely free to download.

• Chillingo has dropped Tiny Troopers 2: Special Ops down to free as well.

• Velocispider is on sale for 99 cents.

• NetherRealm's impressive Batman: Arkham City Lockdown is just under a dollar, too. Excellent price to try that one out at if you haven't.

• Cavern is a roguelike RPG with some good buzz that's on sale for $1.99.

• Big Fish Games' cute and polished point-and-click adventure title Fetch is only $2.99. That's just a buck off the usual price, but the game's well worth it.

• Finally, the retro arcade space shooter Plasma Sky is also available for free right now.

Personally, I'm still enjoying Firaxis' free Haunted Hollow, but I'm loading up a few of these on my iPad as well. Enjoy!
