Here's a trailer you may have missed among the bigger news of E3 2015, but fans of anthropomorphised rat slaughter will nevertheless want to check out. This short Warhammer: End Times - Vermintide [official site] trailer shows off the variety of environments you'll be trudging through with friends once the co-op FPS releases this autumn.
This co-op survive-em-up (think Left 4 Dead) looks pretty fun, and the art style and atmosphere is convincingly Warhammer. Cleaving Skaven beasts apart results in a satisfying amount of gore, which bodes well considering you’ll be chased by quite a few, if the trailer’s anything to go by.
The trailer ends with a glimpse of a larger scale Skaven pursuer. Maybe a Rat Ogre? My knowledge of Warhammer is weak and rusty, so you’re probably a better judge than I. A bit of enemy variety is a good sign though. I wonder if we’ll see more powerful, individual enemies like Skaven verminlords or assassins. Wouldn’t that be nice.
