Ratchet starts his newest adventure with a standard-issue set of body armor, as well as a Deadlock necklace--if he doesn't garner high ratings on a Running Man-style game show (that happens to play like a squad-based shooter), he'll be blown to bits.
Why does Ratchet suddenly look like Master Chief? Is this turning into Halo? Not really, but this series is moving even deeper into action-shooter territory: The entire singleplayer mode is played with a squad of intelligent robots that Ratchet can command and upgrade. The number of weapons has been reduced to 10, but customizable upgrade paths give players a high degree of control over their arsenals. It's more intense and violent than past games, but also more rewarding...especially with a pal in splitscreen offline co-op. And the five online multiplayer modes add infinite replayability.
