Looks like they're celebrating some awards so the game will be free for a limited time. I've heard great things about this one so grab it while it's hot! Says no IAP everything is premium. https://itunes.apple.com/us/app/the-martian-official-game/id1019838009?mt=8
Looks like a blatant ripoff of Lifeline. I'll grab it anyways https://itunes.apple.com/us/app/lifeline.../id982354972?mt=8
