Major Aggressive grab on a human makes you immune to all projectiles

[Infinite Monkeys]

This is intended as far as the code goes, but something we should consider implementing later is a 'bullet penetration strength' variable that allows a bullet to shoot through multiple targets while sacrificing some power for each target passed.

pierces_left does this (projectile_parent.dm)

edit:

Humorously, people holding a weapon while grabbed will also smack themselves instead of you. Try it with a monkey!

Should be fixed now.

As an additional note, if someone is hit from behind while facing forward with a human shield does that still get blocked? I feel it shouldnt, leading to flanking maneuvers from a coordinated crew being effective.

It was directional for melee but not ranged. I removed the direction requirement completely as it doesn't really work with SS13 combat.

This is the intended effect of the "human shield" feature. After about maybe five or so shots, the thing you're grabbing on to will be knocked out of your hand anyway.

As of now this does not happen. 10+ shots did not do this.

Strange; I've had it happen before. Maybe it's just extraordinarily rare?

It was previously a 10% chance for ranged, and melee never caused the grab to be dropped. It's now 20% for both melee and ranged.
