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!
