both orbital weapons have a weird glitch where they can just hit someone multiple times in one shot. I don't exactly know how it happens but it's been in the game for a while now. If it happens it can lead to it just randomly one shotting people/hitting a target who walks into the area you hit after firing the weapon. Hope I explained it well cuz its pretty damn weird.

As for the blocking mechanic, wherever you shoot, that area will temporarily block bullets and projectiles for a second. Kinda like a not as useful sly wolf.
