I need some help identifying a game I saw on a demo a while back.

Its an FPS, the part that I saw is related to the pic. Except instead of stone mountain spiders they were machines or similar size You were on a riverboat that was moving up stream, in a Louisiana type area, you'd pass under bridges and highways and these enormous mechanical spiders similar to pic would pass over you, the riverboat would carry you into the flooded town and there would be creatures inside the flooded buildings that would attack you and you'd have to shoot them. Had kind of a left 4 dead and half life vibe to it. but it was neither of those.

Does this sound familiar to anyone?
