Savage Moon is "tower defence" PSN game
SCEA's released first proper details and screens of Savage Moon, the PSN title shown for the first time at Games Convention last week.
Apparently, "Savage Moon is a frantic, action-packed tower defense game in a gritty sci-fi setting. You are tasked with protecting mining facilities from ravenous space bugs using some truly fearsome weaponry. And you’ll need as much strategy as firepower as you fend off wave after wave."
Space bugs, eh? Loads more through there. It's releasing this "fall".
