Sisters have been covered in the icon mod's second installment based on the new skins provided by the HD skin mod. Now that they've been covered, the next two releases I'll be focusing on are the icon mod and the HD audio mod.
Much like how Sisters were the biggest focus in the release of the audio mod, Chaos will be the next faction with all of their audio remastered (with the exception of weapon sounds).
Another addition to a current project is underway at the moment. My army schemes mod will be having alternate banners replacing all of the factions (16 banners per faction) for Ultimate Apocalypse.
In regards to UA, my main focus for the mod is to apocalyse the maps even further by altering the vanilla maps to include more space as well as making sure each map (mostly larger maps) has a relic, critical location and slag deposit. However, as I've mentioned before, I was working on some skyboxes for each map and I've come to hold off on working on those since they take a lot of time with very little payoff.
Taskbar mod is making a little progress here and there as well. The Sisters taskbar will be my current focus and I want to make sure I finish it before I start making icons related to weapons and leaders (design the overall hud to fit in as much as possible).
That's about it in regards to my work. Hope you guys are looking forward to it.
