Why cant i use Vials or EMP in ENSLAVED already on Level 11

i can see EMP under decoy in corner but have no way to choose it, also i see vial pick ups all over but i am full how do I end up using those? Thanks

Bump Anyone!

I think Trip uses the EMP when she needs it, and the player can't control it. As far as health vials, I don't know what the "vials" are - they mention them near the beginning of the game, but after that the green things are just health pickups and if your health is at 100%, you can't use them.

The EMP is Trips self-defense option. To give you a chance to save her if you failed at keeping the Mechs away. She uses automaticly. The health vials are also used by trip. You have to be close to her and give her the order to use them. Then your health gets restored completely.Reptylus

Weird. I just platinumed the game yesterday and I had no idea you could get health from Trip LOL.
