iOS and Android this week, Ratchet & Clank: Before the Nexus. Free on both platforms, Before the Nexus is an endless runner in which players collect bolts while hopping between grind rails and avoiding obstacles.
The game ties in to Sony's November entry in the main series on PS3, in that Raritanium obtained in the mobile game can be synced with Ratchet & Clank: Into the Nexus, allowing players to upgrade their weapons in the game at a faster pace. Before the Nexus includes a handful of gadgets and weapons from the series for players to collect as well. Given that our review looked fondly at Into the Nexus, noting that it felt like a "farewell" for the series, the mobile companion app may be a worthwhile download for players booting up the main game for the first time.
