Looks like Chris isn’t going to be alone; he’s seen accompanied by a woman in these pictures. It doesn’t look like anyone we’ve seen before in the series, and if the rumors flying around right now are true, a second player will be able to take control of her, and you’ll be able to do online co-op.
Given that the first Resident Evil was originally planned to have co-op, and that it’s a feature that’s never yet made it into the series, the inclusion of co-op in Resident Evil 5 would be a huge feature and would make perfect sense with the series’ propensity for always featuring two main characters rather than one.
And yes, that’s definitely a chainsaw of some sort…
