Prime: Battle for Dominus dev chat this past Friday, fear not! Massively has you covered via the video embed after the cut, and it's chock full of juicy sci-fi pseudo-sandbox goodness (as well as a bit of gameplay footage). The whole presentation runs just upwards of 50 minutes, and the in-game footage features video captures from the current beta build.
Ranged and melee combat is evident, as are several different environments. The devs call attention to the game's three-faction PvP elements, and though the brief clips show relatively small groups of combatants, that will eventually change in favor of large-scale engagements.
Pitchblack also says that it's getting ready to release a few official combat videos, so stay tuned to Massively for the latest and greatest Prime: BFD news and views.
