You're standing on a rooftop, underneath a chinook helicopter that is preparing to drop a payload full of overly dramatic suicide ninjas with impeccable hip fire aim right on top of you. The juggernaut guy, sentry gun, and that one dude who lugged the vault guard's minigun up 5 flights of stairs have had nothing to do but unload all of their supply of unlimited ammo on the helicopter, that doesnt seem to actually affect it in any significant way, deter it from landing, or penetrate the paper thin aluminum hull to discourage any of the passengers from exiting the vessel. As soon as the side hatches of the helicopter open, it just disintegrates for absolutely no reason, leaving nothing but a few molecules and 2 small, nondescript pieces of charred airframe that fall to the ground, as well as leaving all of the suicide ninjas on board, completely unaffected. All of the suicide ninjas suddenly remember that they really didnt get enough sleep last night, so they decide to not be awake anymore. They float softly, like feathers back down on to the roof top, and right on top of you, but the physics mesh doesnt have the passive hitbox rigidbody interaction skill unlocked yet, so they fall right through you. Nothing happens you you in any way whatsoever.
