3. Bug Fixes

Feature Update: Metal Slug Attack Reloaded – Ver. 1.2.0 (Switch NSP)

Prerequisites

To install an NSP update, you generally need a Nintendo Switch that is either:

  1. Modded (Custom Firmware/CFW): Running Atmosphere or similar CFW.
  2. On a Firmware Version compatible with the game update.

Final Thoughts: Should You Hunt Down the "Reloaded" Update?

If you are a fan of tactical auto-battlers with a Metal Slug coat of paint, absolutely. The new Metal Slug Attack Reloaded Switch NSP update (officially version 1.1.0) is a mandatory download. It fixes the most egregious launch bugs, rebalances the roster, and adds enough extras to justify revisiting the Extra Ops.

However, do not fall for shady NSP sites promising "premium unlocks" or "all units unlocked." These files are often outdated, stolen from legitimate users, or filled with malware. The real update is free, safe, and takes less than five minutes to install directly from Nintendo.

To sum up:

Stay tuned to SNK’s official Twitter and the Metal Slug Attack Reloaded Discord for announcements about the next new update. For now, deploy your units, call in a Slug, and show General Morden that the Peregrine Falcons aren’t done yet.

Ready to reload? Boot up your Switch, grab the latest patch, and let the metal slug attacks begin.
