Does anyone know how to use C4 while cloaked?

Whenever I plant C4 while cloaked (whether it's standing or crouched), I de-cloak.

In the "Be Invisible" trailer, it showed that we could plant C4 while cloaked.

Any help or clarification would be greatly appreciated.

It was altered from that video. As it is now, its no longer possible to do (at least without cheating).

You can't really. Usually i throw C4 then run and hide so i won't get shot at then cloak then throw it again. Works for me.

It's not possible, probably due balancing-reasons. It wasn't possible in the first game either in any version (normal, Warhead or Wars). Just de-cloack manually before you plant it.

I figured.

Kinda svcks cause I thought it was such a badass feature to set traps like that.

Same thing with grenades. Kinda silly for C4 and prepping a grenade to pop out of cloak and go to 0 energy.

C4 is kinda useless imo.
