Oterworld Miniatures has just posted pictures of new Giant Ants on their forums.
The pre-view shows work in process shots of two ants in a range of five.
Otherworld Miniatures: Giant Ants
These two are Warrior-class ants and are approximately 30mm long. Now thats some big monsters that will be very useful in lots of different settings and genres, I'm sure.
Also to be found in this range will be 3 smaller Worker-class ants - approximately 20-25mm long. John is currently working on these and hopefully we'll soon see some WIPs, soon.
No release date yet, but I would expect to see them in store early next year.
