Here is the replay of the Ratchet & Clank livestream on PS4. You will discover the beginning of the game with Driftwood and BlimBlim, which will maybe give you the opportunity to discover the game if you haven't played the original version.
@droezelke: it looks good but slower paced and open world doesn't excite me as much a fast paced old school style shooter. The Phobos gameplay and that huge BFG gun giving of that green lighting. (14 Hours ago)
