Just a bump. The path released yesterday included new enemies. Previously, there were goblins, golems, and the mythical spiders which only spawned on super-low levels. Now there are wildlife critters that avoid contact until chased around some, Bears, Monitor Lizards, and Honey Badgers, as well as a new invader type, the Mant which harasses gnomes during the day while Goblins come at night, and the Beetle that spawns similar to golems.
Monitor Lizards, Bears, and Honey Badgers can be hunted, spawn on the map's edge, and provide meat, bone, and hide. A current bug makes Honey Badgers produce 30 meat. Bears are lethal, Honey Badgers a little less so (they're not Giant variant yet), and I haven't faced off against a Monitor Lizard.
Beetles spawn underground, even as shallow as -6, and if left alone will place Cocoons, which will eventually hatch into a new Beetle. They are very heavily armored and very dangerous, but only spawn in the dark. Despite their nesting instincts, they wander quite quickly and will leave their cave.
Mants are killer. Just brutal, they will rip into a gnome base incredibly fiercely and utterly destroy it. They are to be avoided at all costs, even full iron and steel armor doesn't help a great deal. I suspect firearms would work well, however.
Goblins also arrive with Ogres sometimes as well. They're bigger and beefier, but don't wear armor.
Goblins and Trolls can be butchered for meat, bone, and hide, although the player must manually order the corpse to be butchered. Troll Hide is the toughest form of leather available, although it's not as good as metal it is much lighter, perhaps suited to wall patrol and musketeers.
All factions are hostile towards each other. Goblins+Ogres, Wildlife, Golems, Mants, Spiders, and Beetles will all naturally attack each other. It may be entirely possible to defend yourself by letting the goblins and mants kill each other!
