Hi crysis
I have a problem in the campaign, I can′t unlock a last module ( in my case "Air Stomp") i need 3 nanosuit upgrade modules for unlock it and only i have 2, the problem is that already i have all modules of the campaign, in the statistics shows me 15/16 Nanosuit Upgrade Modules, but I have finished more of 3 times the campaign in search of the last Nanosuit Upgrade Module and can not find it, I have watched videos of the location of the modules and I'm very sure I have all, but I can′t unlock (Air Stomp) maybe it's a bug in the game? or What's going on?
I hope can me help.
Thanks and see later. Greetings.

I hope they understand my English
