After realizing the shotgun hallway was just way too messy, and that the splinter grenades caused more trouble than I'd like them too, I decided to completely remove the hallway and replace the splinter grenades with the shotgun. The map now has:
2 DMRs
1 shotgun
1 Hydra Launcher
2 ARs
2 Sticky grenades

I also fixed the crappy map barriers lol
