I purchased EMP grenades today thinking that they would have some sort of effect on vehicles however I'm not sure if this is the case having done some initial trials. Has anyone done any extensive testing on this? I haven't played PS1 for ages but I seem to remember the grenade in that version locked up the vehicle completely for about 10 seconds. Being an EMP that seems like it would be an appropriate effect. As it is I don't think the current infantry focused effects are really good enough to replace a standard grenade.
