Batman has used explosive batarangs before, hell, he's even used grenades. They arn't strong enough to kill people though. I just want to be able to get the same effect as explosive gel in open combat.
Batman has used explosive gel and shaped charges as well as small non-lethal mines for detonating structures as well as Batarangs with minimal explosives to knock down a wall.. He has NEVER thrown an explosive device directly at a combatant because that could be lethal.
A Batarang that sends an incapacitating electric shock that can knock you out is a different story.
It should also be known to those of you that haven't played Splinter Cell, the OpSAT also includes software that allows for hacking of security cameras, electronic hacking of keypad locks and electronic locks.
Also a set of lock picks or maybe an electronic lock pick would be awesome.
