Hungry Shark Evolution - This game will have you grow different breeds of shark one at a time into full size, speed and bite by consuming various aqua life species and unsuspecting humans. It has to stay away from harmful species and needs to constantly feed. There are collectibles to scour for deep in the ocean, leading to unlockables. Touted to be Xbox Live aware but I'm having problems having it reflected against my Gamertag playlist. Free to download. No IAPs.
