Indie survival sensation Valheim recently dropped a trailer for its massive upcoming update Ashlands, set to feature a Hell-like world full of terrors. The expansion is available for public testing and will be free for everyone to enjoy.

Developer Iron Gate published the trailer on April 22 and described the new Ashlands biome as “Valheim‘s most challenging biome yet,” implying lots of trials and tribulations await in its infernal lands. The trailer features all sorts of creatures, from reanimated skeletons to decrepit Norse-inspired ravens to flaming giants and Lovecraftian sea monsters. It appears to have tons of diversity in setting as well, with parts shrouded in a thick and eerie fog and others engulfed in a hellish flame and flowing lava.
