Rochard, a physics-based puzzle-platformer from Recoil Games and Sony Online Entertainment, feels familiar in many ways. Using a weird physics engine to grab boxes, take out enemies and make it through various rooms? Yeah, that feels like Portal. The very science-y, futuristic aesthetic? It reminds us a bit of ‘Splosion Man. Even that main character’s voice: it’s Duke Nukem himself, Jon St. John.
