Thanksgiving app sales: Com2Us titles, Puzzle Quest 2, Infinity Blade on sale already

We've already seen a few app sales already this month, but companies are now starting the windup to the big Black Friday holiday, and things are going to get chaotic. Starting this weekend, and rolling on through the Christmas holiday (and even up to New Year's), new iPhones and iPads are going to be making their way as gifts into lots of consumers' hands, and that means that app developers everywhere are going to be fighting tooth and claw to get their apps installed on those new units.

That makes it much more important to get into lists like the Top 50 paid and free apps. When Apple "freezes" the store for developers over the holiday, what's on those lists stays there, so there's even more incentive to sell. We're aiming to track app sales as much as possible -- stay tuned this week and all holiday season long to our holiday gift guide to see what's dropping and on sale now.

In the meantime, here's what's already on sale this week:

• Hand-drawn adventure game The Train has dropped all of its episodes down to 99 cents.

• Developer Com2Us has put lots of its iOS titles on sale for a buck, including Homerun Battle 3D, Inotia 3, and Tower Defense: Lost Earth.

• Gameloft is also underway with a sale, including Eternal Legacy, the Gameloft Action Pack, and lots more for a buck as well.

• Infinity Blade is down to $2.99, both for Black Friday and because its sequel will be out on Thursday of this week.

• Konami's charming Gesundheit is down to just 99 cents, as is Pro Evolution Soccer 2011.

• The really fascinating action RPG title Fara is also just a buck.

• Namco Bandai is planning some big sales for later this week, but Puzzle Quest 2 is already discounted to $2.99.

• Breaking Art's Morning Motivation is down to $1.99 from $5.99, which will help with those post-Thanksgiving crises of gym dedication.

• The Comixology app has all 12 of the old Marvel Secret Wars comics on sale for just 99 cents each. Perfect time to catch up on some classic comics.

• Mortal Skies 2 is completely free today as well -- it's a pretty well-done shmup for iOS.

• The Wave Ride-esque Riptide GP is still on sale for a buck from last weekend.

Stay tuned -- we'll probably end up doing a post a day this week about all of the various sales starting up on the App Store, so come back every day to see what a dollar can get you for great software on your iOS device.
