Even with what most companies would consider a vibrant community, NM Fun had thousands of players asking for high-quality written guides for the game. It was hard to find the exact information you are looking for by scrolling through a video. In addition, the databases that were online-only provide stats, not strategies.

GamerSpeak had been in talks with NM Fun before the English version of the game had launched about building a community for their game. With such a strong title, NM Fun wanted to wait and see what sort of community would arise naturally from the player base. In the first few months, multiple large Youtube channels (5,000+ subs) and two database sites were created for the game. There was also a strong presence on Reddit with over 30,000 subscribers. Yet the challenge of creating in-depth professional strategy guides hadn’t been addressed.


GamerSpeak created long-form, in-depth, and high-quality strategy guides for NM Fun using the Fandom wiki platform.

The key objectives for the content in priority order were:

  1. Content covering general info on ALL the components of the game:
    • All Heroes, Map Levels, Team Suggestions, Buildings, PVP, PVE, Equipment, Etc.
  2. Content to assist the progression of their core engaged audience who had been playing for 30-60 days
  3. Content to help players get the most out of new features and events launched every week
  4. Content that would shed light on hard to discover portions of the game


Since the game had already launched, GamerSpeak had to quickly publish content as fast as possible. NM Fun was incredibly responsive, providing us with assets and game stats that we needed in a timely manner. Within 45 days we had 225 unique pages of content published on the wiki!

Impressed with the quality and speed, NM Fun requested all the content to be localized into German, French, Spanish, Portuguese. They used their localization partner, and GamerSpeak created the interlanguage language wikis and published the localized guides.

The Wiki launched on May 26th, 2020 to very positive feedback from the community.

Two months later on July 31st, 2020 NM Fun was ready to share the Fandom directly to their Forum with 220,000 global users. At this point, we published 75 localized guides (~20 in each language) that allowed the content to be available to a large portion of the user base.

The post was super well-received by 3,400 viewers in the first 5 days, with 33 positive reactions and only 2 negative reactions.
