Cutting down the issues! We're now largely dealing with shader and material glitches that have cropped up in switching to Unity 5, many of which are not immediately apparent until running a mission and encountering this...

So we're fixing these as we find them. Another issue is how 5 handles materials and lighting, so all of our maps and rooms will need to be relit. Fortunately this is largely just time consuming and gives great results.

Also... Rare Spawns are in! Each mission will have a chance to spawn a rare mob, with increased chance on difficult game / mission settings. Rares drop improved loot, have unique abilities, and are tougher than average mobs. They're also randomly generated. Here's a Chrome Watchdog with two regular Mark I drones.

Our goal is to have everything in place to test very soon and we'll be putting out the update once we're sure everything is stable. In the meantime - work continues!
