Survival Saga
Survival Saga—often called Saga or Saga Zombies—is a short progression event built around defeating increasingly difficult zombies.
Choose a difficulty, complete every challenge in the current level, then defeat the Saga Zombie to advance. The event is simple; the important decision is choosing the difficulty you can realistically finish.
How It Works
Clear the level, defeat the boss, repeat.
Each level contains specific zombie targets. Once those challenges are complete, the Saga Zombie becomes the final gate before the next level.
01
Difficulty Choice
Normal or Advanced
Choose once at the beginning of the round. You cannot change modes afterward.
Advanced
Fewer stages, but much stronger enemies and a higher power requirement.
02
Simple Game Plan
Five steps to finish efficiently
Choose carefully
Pick Normal or Advanced when the event opens. You cannot switch difficulty during that round.
Clear every task
Complete the required zombie challenges for the current level before moving forward.
Defeat the Saga Zombie
After the level tasks are complete, defeat the Saga Zombie to unlock the next stage.
Rally when needed
As enemy strength rises, team up with alliance members instead of wasting attempts on solo losses.
Claim as you go
Collect milestone and difficulty-completion rewards before the event closes.
Rewards
Two reward tracks
Survival Saga provides milestone rewards within each level and larger rewards for completing difficulty stages.
✓Universal Orange Hero Fragments
✓Orange Skill Books
✓Universal Purple Hero Fragments
✓Gold and Badges
✓Purple Food Level Chests
Do Not Get Stuck
Use alliance rallies when solo attacks stop working.
Later Saga Zombies become significantly stronger. Ask for help early rather than burning time and attempts against a target your march cannot defeat alone.
