Not at all, zombies have tons of hidden features. Build able guns and machines, different types of enemies, easteregg glory, hidden perks/perma/persistent perks. Zombies isn't about just killing waves anymore, you solve riddles and puzzles that take 4 people and exact timing. If you think the "hidden" quests in Destiny are cool - like the Sleeper Simulant, then be aware that the riddles and steps in the zombie eastereggs makes these things look weak.
