One of the higher profile games that will be shown at E3 by Sony is a PSP version of Ratchet & Clank. However, Insomniac isn't developing the game- it's been entrusted to High Impact Studios and will be their very first project. While that kind of news would make some Ratchet fans nervous a number of the people at High Impact are former Insomniac employees and have worked with the previous games in the series.
The game will have the series' usual array of weaponry/ gadgets and travels to various points in their universe. A somewhat new addition will be an armor customization feature and a number of vehicles which can be used in races and missions along with up to 4 player wireless multiplayer.
Just another couple of weeks until we see more setails on the game- I know I'm interested!
