That was already what it was in the original Crysis. I think in this game it only activates when you press jump twice or melee. So I think they took it out. Nanosuit 2.0 seems like a downgrade.
Hmm alright, I didn't notice that in Crysis, but I didn't use is very much

And hey, I didn't know that, thanks

it was HUGE in crysis 1/wars
was awesome
