Refering to the living dead playist I simply had a suggestion for 343i.
Of the three choices for the game and map i think they should be arranged in like this.
User Modified map with Infection or Alpha zombies
An original map with the infection game variant
An original map with the Alpha Zombies game variant
None of the Above
This is all so that you are not force to play infection( which in my opinion is not as fun as Alpha Zombies.) And so that you dont have to play aat a custom map like uncongealed,in which the games are extremely short and no fun at all.
Any Opinions?
