Halo 4 Mythbusters Episode 5

These are always cool. I wonder how long those needles will stay on a vacant weapon. Like can you shoot a sniper a bunch with a needler and walk away? Next person to pick it up will blow up?
 
yeah i always watch these when theyre posted, it's like, consistently a learning experience every time. Needlers ftw

and i dont think needles stay longer than a couple seconds, like when you have one or two in you. it might be different in weapons though
 
Yeh, theres a couple little things in this episode I wish they would have dug a little deeper into. Like the overshield/binary rifle one. The overshield, at least in previous Halos, always granted a 4 second invincibility. I'd like to see if the binary rifle killed the player after those few seconds had passed.
