Given that Predators have a long history of spear guns going all the way back to Predator 2 (even though we never got to actually see it), I'm super glad to see it looks like some type of spear gun rather than just a bow or crossbow with Predator-style texturing.
I'm still not entirely sure how the targeting lasers are going to work with it since they're attached to the helmet as usual but this looks like it's going to be a hand-held weapon, but I'm definitely looking forward to seeing more of it in action!
