From the post:
On October 23rd The Ion Age will be releasing the range of 15mm Espaten Portable Weapons along with two packs of gunner crew for them. This Sneak Peek is an overview of just what you can expect. It is also in place of a weekly release from us. What's more we will be having a release offer on all of these codes for a week after release saving you 15% off the regular prices.
What could be more awesome than that, eh!?
