The problem here is I still can't find Lost Towers mission.
I think now I'm about 5-ish months into the campaign, and I already got advanced mag weapons, Exo suits, predator armor, plasma grenades and stuff like that. I got my DLC from Steam (alongside with the game itself and LW2 of course), and I started a campaign in LW2 1.2 (on rookie level, for what matters). First things first, I have to apologize in advance for my very poor english level, I'm italian so I might be mistaking from time to time.
