Two iOS games more suited for October than January have popped up for free in the App Store. Puppetz is a platform and dual-stick shooter game where players control and fight various evil puppets. The game offers 21 unique playable characters, and loads of missions, unlockable weapons and achievements.
I gave the game a quick whirl and I wasn't terribly impressed. However, I'm not a big fan of side-scrolling shooting games on the iPhone, and I honestly didn't give it much of a chance. Fans of creepy and cartoonish platform games may enjoy it more than I did. The game is 100% free with no ads or in-app purchases. Puppetz is compatible with the iPhone, iPad and iPod touch.
I attempted to play Undead Slayer, but it refuses to play nice with jailbroken devices. The game has mostly great reviews, but I noticed a few complaints about it being heavily geared towards in-app purchases. If you don't have a jaibroken device, and want to give it a try, it's free to download for the iPhone and iPad.
The game description promises 90 stages of "hack-and slash action" and 20 unique skills with dazzling effects, but I'm not sure how many you get for free. The entire game was created and designed by one developer -- who obviously frowns upon jailbreaking.
