In the wake of iTunes Connect returning to operation following Apple's holiday hiatus, a massive wave of updates have been pushed out. These are just a few of the notable updates, but even if you don't own any of these games I'd still check for updates as I just downloaded a metric... truckload.
Hook Champ - Hookbot has been added, a new playable character available via a 99¢ in-game purchase. When you play as Hookbot there is no ghost chasing you, and he also has a recharging steam powered thruster that works a lot like the gun on normal characters. A new costume system was added that allows you to even further change the appearance of your characters along with new hats and a upgrades at the in-game store. (Review, App Store)
Zombieville USA - Play as one of 7 new characters which all look different and provide a different spin on gameplay such as some characters having more health or different movement speeds. Level selection was also added along with checkpoints you can return to once you've reached them. (Review, App Store)
Doodle Jump - An enhancement to the existing holiday themed snow update, there is now a new yeti monster boss that has to be shot down with snowballs before you can jump on the two platforms he hogs up. (Review, App Store)
Red Conquest - Quite a few of the complaints we had in our review have been addressed, an additional tutorial level does a great job at explaining the basic tactics of the game and the difficulty curve was lowered for the early levels among other improvements. (Review, App Store)
Jet Car Stunts - A new in-game tutorial really clears things up for new players, and a new casual and much more forgiving game mode has been added to both platforming and time trial game modes. You can also now change your camera view during replays. (Review, App Store)
iBlast Moki - New levels, new graphics, a completely redesigned level editor, and a new "Doodleland" world make this great game even better. The tutorial has been improved, along with other bug fixes and tweaks. (Review, App Store)
