The Red team castle from Fat princess, The Priests, Giants, Wizards, and workers lounging around inside. Then some blue team guys come over, but get chased away. All is well, then the sky goes dark and a green mist falls over. Tombstones pop out of the ground and gargoyles come out of the castle walls. Zombies from MediEvil bang on the castle doors, smash in, and turn the workers into zombies. A few remaining workers throw bombs at the crowds of zombies and they going flying and bonk into the platforms.
The crater from Infamous one where the Ray Sphere was, the Ray Sphere in the middle. It starts shaking a little, the ground sparks a little. Some electricity shoots out onto the platforms. There are train tracks from Infamous 1 in the near background. The train from Uncharted 2 comes shooting down the track, Derails, and hits the ray sphere. It rides off screen. Then it comes back closer, and hits the platforms, sending everyone in the air. Everyone is then riding the top of the train, with the occasional guard inside sticking his head out and launching a rocket.
your 1st idea is VERY cool. it would be funny stage and we need a stage of medievil and FP.
your second idea, mmm.... nope. we already have an Infamous stage, so why another? :/
At least one for Infamous 2 (New marais)
I like the idea of the Uncharted Train.
I also like my idea of an Unfinished Swan/Journey mashup stage
