The team at Insomniac Games isn't using the recent release of Ratchet & Clank: All 4 One as an excuse to just sit back and relax. There are more video games to be made, after all. The studio is currently working on a game called Overstrike, its first multiplatform release, and new trademarks suggest that another project might be in the works as well.
Recently discovered U.S. trademark registrations for "Space Beasts" and "Galaxy Beasts" are connected with the developer, Siliconera reports. While those terms could relate to any number of things, the filings narrow the possibilities down to video game software and/or online video games. It could be another multiplatform title, or perhaps a name change for Overstrike, but I think it's more likely that these titles connect in some way to Insomniac's recently established mobile/casual division, Click.
