What ever happened to the good old 'zombies' when it wasn't near impossible to survive a full round? Don't get me wrong I like the idea of flood instead of zombies (we can let call of duty take that) but why in the world would you want to make it so impossible to actually survive a round? All the fun of halo 2 and 3 zombies has been completely removed by giving the flood shields and the ability to launch themselves 50 feet at you within a second making it borderline impossible to live? I know this may seem trivial to most but I remember playing halo 2 zombies in custom games and it being the best thing since sliced bread. I had more fun in those custom games than I did most matchmaking games. Back when you weren't fighting against 'predators' and the humans actually had a fair shot at at least having some fun. Just some food for thought I guess.
