Generals!

Welcome to Operation Brainstorm - File .: 1.16.6 :.

This is the release of the final part of Expansion Pass 1: Prototype Vehicles. All of these models were either blueprints or early prototypes that were created or designed during the war, but ended up never getting used, or even manufactured. Also, they’re all entirely optional to use. Everything in this Unit Pack is intended to add some flavour and doesn’t affect gameplay.

To facilitate and accompany this release we have included a War Effort patch, tweaking some balance, as well as fixing a bunch of issues.

I hope you enjoy this release! Our current plan is to be back in just a few weeks to give all of you more insight into what we are, and have been, up to.
