>>524044872k's launcher fucked my modlist to hell so I can't really give a comprehensive list of everything I ran at once. I basically just stacked like, every mod that increased difficulty on top of each other that I could without the game crashing. End result was large enemies getting into the triple digits for hp toward the endgame, aggroing one pod aggroing all the others, shit like taht. Also stuff like almost totally randomized classes, higher squad size, and no time limits (beyond the enemy reinforcements eventually becoming too much to handle obviously). Very fun, highly recommend.
