No me deja usar el arma principal del infiltrado y he estado esperando durante días, pero no se arregla. He doesn't let me use the main infiltrate weapon and I've been waiting for days, but it doesn't fix.
Not a bug. It's Stalker Cloaking. Cloak does not drain while stationary, but prevents use of primary weapons while equipped.
They really should do something to the UI to show that weapon slot disabled. I bet as soon as they put a red cross over the primary slot, they'll stop getting these bug reports
