Whether you're more a fan of teaming up with friends for co-op games or going toe-to-toe with them, we've got a pair of free games to suit your multiplayer group's needs. This week, you can grab a co-op game inspired by the legendary Marvel vs Capcom fighting games, along with an arena fighter featuring some familiar faces, and it won't cost you a thing for either. If you're looking for some silly, fun games to gather your family and friends around this holiday season, make sure not to miss out.
