It's definitely cool to see the speargun get some love. It's hard to tell if it's a wrist spear gun like in P2 or is it more of a handheld weapon?
Also, those downward facing Mandibles are definitely unique. It will be interesting to see if the "new look" is pulled off in the end.
That edged weapon is cool. I hope all of Feral's gadgetry isn't completely spoiled before the movie arrives.
