Gameinformer has 30 minutes of the game. 
 
Seems to be getting some hate which I guess Resistance always has. I remember GB staff saying it looked bad at E3. I personally think it looks quite good but I enjoyed both Resistance games. Still stand by that it looks better than Killzone 3 which was disappointing to me.  I only dislike the grenade throw animation...looks weird.

Insomniac should stick to making cartoony 3rd person shooters. None of the Resistance games have been that great and it just feels so wrong of them to keep making them.

I can't be bothered to copy that link to the address bar, that's how much I care about Resistance.

All I care about the Resistance series is their "Glass Breaking" technology. Everything else.... nah.

I dunno man, the part they chose for the E3 demo looked boring as fuck, just straight up bad too...
 
This demo looks better though, something about resistance movements and guerrilla warfare appeal to my sensibilities.

I never liked the campaign as much as the frantic multiplayer. All those people in one battle made for a great experience.
