Raid: Shadow Legends

Battle your way through a visually-stunning realistic fantasy RPG with hundreds of Champions from 16 playable factions. You must train them to fight together, mold them into living weapons, and assemble the greatest raiding party ever seen.

Raid Shadow Legends is a free-to-play tactical mobile game focused on party turn-based combat. As a player, you will build a team from a huge roster of more than 400 champions, each with their own unique appearance, skills, and equipment. From there, you can embark on a huge range of missions and dungeon raids seeking out greater foes and greater treasure. Available on all mobile devices, Windows, and Mac, build your team and set out for glory.

The Cyrex team really enjoy working with Plarium and we were delighted they trusted us to conduct full-scale White Box penetration testing on Raid Shadow Legends. Created on Unreal Engine, we tested the game on PC & Mobile and the live services were a focus.

Core Features

Some of the core features we tested included:

  • Reward system
  • In-game shop
  • Upgrade system
  • Building system
  • Chat functions
  • Heroes & Characters
  • Artifacts 
  • Daily bonuses
  • Battle system


The team at Plarium were thrilled with our results. Given such a comprehensive and deep dive into their source code, we were able to uncover several vulnerabilities which were addressed and solved at the highest priority. Thanks to the access of the White Box testing, the Cyrex team could give Plarium a full rundown of their code’s weak points and how they could address them. It was great, as always, working with the Plarium team and we’re looking forward to any future collaborations.
