Second Chance Heroes for iOS lets you fight sentient burgers with a chainsaw-wielding Abraham Lincoln
In case you haven't noticed, the plot is a satire of 21st century life's cultural staples, which inspire "an apocalypse of the absurd". Indeed, there's nothing like paying homage to our burger-less and TV-less past like putting you in the boots of Nicola Tesla armed with a Ghostbusters-like ray gun. And this is only one of the options. The two starting characters in the game are Abraham Lincoln and Cleopatra. You already know what Honest Abe's heroic powers are (wroom!), but Cleopatra fights using her perfectly preserved charm, along with magic spells and her golden staff.
The rest of the characters have to be unlocked separately with in-app purchases. You will have Joan of Arc, Napoleon, Queen Elizabeth I, Nikola Tesla, Julius Caesar, Blackbeard, Marie Curie, Montezuma, Leonardo da Vinci, and Genghis Khan at your disposal. Each character can be upgraded in exchange for Relics and experience points. Be aware, though, that "Relics may or may not summon magical toilets that smite your foes." Also, you should pay a visit to the game's official website for in-depth overviews of each character, and additional hilarity.
Second Chance heroes has 26 levels and roughly ten hours of gameplay in single-player mode. Currently, the game is available on all iOS 6.0 devices (iPhone 3GS or later, iPad 2 or later, iPod 4th gen or later) with PC and Mac releases in the works.
