Resistance 3 screeshots posted below the break are of a train yard, and Joseph Capelli and the Chimera are trying to kill it each other, apparently.
A video posted below culled from the PS Blog is posted below as well.
Those are PlayStation Plus subs should look forward to a demo of the game in the near future. Sony has yet to say when it will drop.
The game itself ships for PS3 later in the year.
High resolution screens can be found through the link above.
1UP has also posted a preview which chats about the 11 things in Resistance 3 that weren't in the series before.
Apparently, these 11 things are: Lots of civilians, an unscripted A.I., down time, simplicity, invisible snipers, multiple paths through a level, weather, more detailed storytelling, shield drones, killstreaks, and two ways to play instead of three.
Thanks, Gaming Everything.
