Predecessor

Client:Omeda Studios

Cyrex partnered with Omeda Studios to conduct black box penetration testing for Predecessor, securing Unreal Engine 5 networking, live services, and core multiplayer gameplay systems ahead of continued PC release.

The Challenge

Securing a Competitive UE5 Shooter-MOBA Hybrid

Predecessor blends the intensity of an over-the-shoulder shooter with the strategic depth of a MOBA. Built on Unreal Engine 5 and released on PC via Steam and the Epic Games Store, the game depends on secure multiplayer infrastructure and reliable live services.

Players assume defined MOBA roles — carry, jungler, solo-laner, support — and engage in coordinated team-based combat. In competitive titles like this, vulnerabilities in gameplay validation or service infrastructure can directly impact balance and player trust.

Omeda Studios required an external, attacker-perspective evaluation of their systems prior to broader scale.

The Cyrex Solution

Black Box Penetration Testing Across Live & Gameplay Services

Cyrex conducted comprehensive black box penetration testing, evaluating Predecessor without access to internal source code.

This methodology mirrors real-world attacker conditions, assessing how exposed services and gameplay systems behave when probed externally.

Unreal Engine Networking & Gameplay Assessment

Our engagement focused on:

  • Physics and shooting systems
  • Character management logic
  • Reward distribution mechanisms
  • Matchmaking infrastructure
  • Chat systems and player interactions

We tested live services and gameplay networking to identify potential exploit paths that could be leveraged without insider knowledge.

Real-World Attack Simulation

Using a black box approach, Cyrex:

  • Interacted with exposed endpoints and gameplay flows
  • Attempted manipulation of gameplay-related interactions
  • Assessed authentication and session handling
  • Evaluated server-side validation boundaries

The objective was to identify vulnerabilities from the same vantage point available to malicious actors.

The Outcome

Validated Multiplayer Integrity Under Real-World Conditions

  • Identification of potential exploit vectors across gameplay and live services
  • Remediation guidance for exposed weaknesses
  • Improved confidence in Unreal Engine 5 networking security
  • Reinforced protection of matchmaking and reward systems
