I remember getting really excited over this video that we’d get the Spiker (maybe the Brute shot) back and a few never before seen Brute weapons. All of Halo 5’s dlc has come out by now though and everything else in the video came to the game, everything from other video like this by Gamecheat13 came to the game, the files are there but what happened to these 4 weapons?
The files should be still there,but they never made it into the game and that most likely wont change.
Not everything that gets put into a game or application ends up making it into the final product. You’ll always come across partially created items that didn’t quite make the cut. perhaps there were plans at one point to release these, but at this point it’s very likely not happening
