Faceroll Games, who developed Call of Duty: Heroes [Free], are hard at work on an original title called Monster Metropolis. They're describing it as Sim City meets Rampage meets...Grandia? Yes, that's the plan here. You'll be building up a city of your very own, and trying to protect it from your many, many enemies. But you'll also have a bunch of different creatures to collect and upgrade. And then, you'll do battle with them against opponents in JRPG-inspired battles, including raids of opponent cities.

I'm interested to see how Monster Metropolis shakes out in this hybrid city-building genre that keeps popping up,even with other, similar hybrids like MonstroCity [Free]. But, the RPG battling elements could prove to be the big differentiator here, especially name-checking Grandia specifically. Curious about this one? The developers are looking for beta testers on our forums.
