As a bonus they were having a 3 for the price of 2 sale and after a bit of browsing I decided on these three pieces. First up is a ruined Greek style temple as shown in the picture below. The models shown in the pictures are a Rebel Minis 15mm Mech and some 15mm infantry.
I suppose this temple could be used on any 15mm or even 28mm board as it's the least alien of the three. Perhaps as part of a Strange Aeons or Malifaux game.
Next up is the skull. This is obviously too big for a normal 15mm game but perfect for the remains of some giant alien beast!
Last up is a piece described as a volcano but it works well as either an alien rock formation or some kind of alien plant.
All the pieces come prepainted and are made from a durable looking hard resin. The total cost of the three pieces was £10.99 which I think is a pretty good deal considering their size. I may even go back for some more.
