Yep. Early game, you accidentally time travel to the past. You fix what got broken by the time travel incident, get back, and go through a kangaroo court. You escape from that, find another portal, and after fighting your way through some futuristic ruins, you find out this mountain-sized porcupine-looking thing with a graboid head erupted out of the ground shooting lasers everywhere, and the rest of the game revolves around preventing that.
