I think it was Choco who managed to time a nade just right so that the crate would move. The issiue is you have to hit it just right while its still in the air, once the parashute is off, the crate won‘t move.
Yeap! They don't move after a touchdown anymore
You gotta find them e pickups and have it handy for this situation.
Yeah, that or become a frag grenade master!
