The Warhammer Online folks are keeping sort of a low profile this week, but in honor of E3 they have released a brand new trailer highlighting Realm vs. Realm combat. The video, which is embedded below the cut, shows off the on-foot combat, as well as siege warfare. Siege warfare is the core of the game, with the recent city areas cut not affecting the basic rolling combat that will ultimately overwhelm the two remaining capital cities. Make sure to check out our own coverage of the game's PvP elements as well. They include our look at RvR scenarios, a look at the keep and siege warfare, and what it takes to sack a capital city.
