New Resident Evil: Operation Raccoon City shots feature zombie-shields

Would taking a zombie as a hostage and using him as a non-human shield buy you any time against other zombies? That’s a question Resident Evil: Operation Raccoon City looks forward to answering.
These new screenshots show just such a thing being done, as well as a big scaly beast and our good pal Leon (who seems to have got over his confusion just long enough to point a gun at something.)
Most of the images look like captures from cut-scenes to me, but they do give a few more impressions of the four-player team shooter antics.
