Voodooworx have added an Oval Alien Temple Base to their online store.
From their announcement:
We have had loads of emails recently asking for us to release more base sizes for our Alien Temple theme. So this month we are proud to announce the release of our new 120mm x 90mm oval Alien Temple gaming base. Priced at just £6.00, it is available to pre-order on our site right now and will start shipping Monday, 6th June. Use it to base larger miniatures for your games or even as a display base for a vignette or diorama.
Just to let you know, we also have two new 60mm round base variations on their way, the first of our round lipped bases in the same theme will be ready very soon, plus the first sets in our new gaming base theme are nearing completion too. So a very busy couple of months coming up.
