Just released Version 020 on the mod.io page! This is mostly fixes for bugs that came to light in the previous release, but there is new content such as Tanith Imperial Guard gear with sprites by Lord Flasheart, and enemy ground vehicles showing damage when "shot down" by your craft!
After reading the codex, tried it out on highest difficulty with the default weaponry, giving my soldiers 'insta-explode' grenades in both hands, one grenade/rocket launcher and the default lasguns. Scouts shot my skyranger to smithereens so I stormed a landed "scout". Many enemies. I killed about 70% of them and took the grenades from their fallen, but when I finally approached their ship with my beaten up squad, those turret guns made short work of my people. I simply couldn't get through and gave up.
Now I'm trying a similarly landed scout mission with a sniper rifle, rocket launchers and heavy bolters + grenades.
Still have no idea how the hell to destroy those MOFO ship turrets. Those were a magnificent idea, whoever created them!! Completely changed the gameplay.
