The darkly atmospheric title Gemini Rue, released this week on iOS, has dropped its price to $3.99 for two weeks. Its original price is listed at $4.99, so if you want to save 20% now's the time to open up that piggy bank.

Originally released for the PC in 2011, the story centers on Azriel Odin, a former assassin in search of his missing brother. When his luck turns sideways, Odin must seek assistance from his underworld colleagues.

Wadjet Eye Games co-founder and programmer Jane Gilbert spent eight months working on the iOS port. Taking obvious inspiration from the sci-fi noir Blade Runner, Gemini Rue is a critically acclaimed PC title, and hopefully those high standards will be experienced by iOS devotees.
