Flood will almost definitely be in Halo 5 and it is with certainty that they will give you the option for Flood to use different weapons, but that’s not what this thread is about. I’m here to talk about Hivemind!
Hivemind is a vastly superior version of Flood/Infection. Instead of either making zombies weak and letting people with shotguns and pistols kill farm (Halo 3/Reach) or making zombies too strong (Thruster Flood) this mode put both sides on relatively equal footing so that they could battle it out. It was more like traditional Halo than any of the other modes because it encouraged people to work as a team to move around the map for weapons, it felt like a true Halo survival game.
In Halo 3 there was no real survival element to matchmaking infection. Save One Bullet was just difficult because your pistol was weak and the shotgun couldn’t kill a shielded target outside of point blank range. Brains was sort of a spawn kill fest as was Speed Demons. And the last one with the invisible gravity hammer zombies was just an action sack gametype (human rocket starts). In Halo Reach, Alpha Zombies was just like speed demons; fairly spawn kill riddled. And we all know what happened with Flood.
Hivemind on the other hand gave the zombies the agility they needed, but made it so they needed to hit a human twice to kill. In turn, humans had ARs and Pistols to defend themselves until they searched for better weapons. On that note, you could actually go look for better weapons and abilities! You weren’t just stuck with a shotgun, you had to find the shotgun, or the sniper, or the concussion rifle! So zombies wouldn’t kill you, you also could kill them in one melee attack. In teams, you could hold out for a while and it was just fun watching your teammates valiantly die and then you go for a sprint with their fallen weapons until the Flood finally get you.
This gametype just has so much more to offer than the base Flood mode or any other pay infection mode really. That’s why I think Halo 5: Guardians should make Hivemind the default Flood mode.
