Speaking of ****** up "Simple Campaign" There like no attack or alarts on my map area! just blank nothing! well, for few minute I lost because my dept is getting too low like minus!

I was thinking that was a bug but I couldn't tell if it is or not!

You should make it so that if there is a BIG infestation, you can evac citizens, and then hit the area with missiles and/or guns.

got to admit, the video at the top didn't tell me anything, just that there is an awesome globe in the game.

I am having a bug problem with this game, and not really good at reporting them, but during campaign on the battle area, as the encounters get longer, when I hit end turn, it will go back to the geo-sphere right before accepting the mission I was just cuurently playing.

Any plans to move from 2.3.1 amd64 for linux to later versions here on desura anytime soon? I only see 2.4 and thats for windows. Yet in my repos for Fedora I see 2.4.1. I like the idea of showing support via desura to know us Linux users are out here but Im perfectly fine with just using the repo download or using the source directly. Whatever the case, just want to also again reiterate, great game, great work, please keep it up and if you ever decide to look for funding you got it from me.

Perhaps one thing to note is the repos version of 2.4.1, for me, no text from intro or mail, etc appears. For example, the introduction text shows as "intro_sentence_1" 2 3 etc. Mail is blank with blank icons and so forth.
