halo 4 albeit all its mistakes did Infection/flood/zombies/whatever else you call it… H4 did a great job of it - the foe was scary. I knew as a human that these foes were not to be messed with up close, with the enhanced lunge distance and one shot kill melee weapon. The Infected/flood/zombies/whatever in Halo 5 are not scary. Especially when any monkey can spray and prey across the map and get a kill. This coupled with BS maps designed with hiding spots for the humans severely handicaps the flood/infected/zombies/whatever. I believe like 343 that the Alpha flood should have a boost to encourage going after the humans, but the buff should only last one life - would not be against making it even higher of a boost maybe two shotgun hits to kill. Weapon pick ups? come on… the humans already have the advantage of distance weapons and the foe’s lack of shields, now they get OP weapons as well? the game should be balanced,or in the Flood’s favor, make the Infected scary again. Make the Zombies something worthy as an opponent. make the maps to encourage movement not hiding like a… (this is a public place so I will refrain from vulgar terms 
…make infection something to be respected as a gametype.
