Zombie Army 4: Dead Zone

  • Performance tweaks: Improved frame rates during the “horde swarm” moments.
  • Bug fixes: Squashing co-op connectivity drops and save-data glitches.
  • Amiibo support refinements: Smoother unlocks for cosmetic items.

Update installs, but version still shows 1.0.0.

  • Cause: The update NSP is for a different region than your base game. (e.g., Base is US, update is EUR).
  • Fix: Match the base game and update regions, or use a “crosstick” update (rare for this title). Better yet, find a base+update combo from the same scene group.
