Designing for Tamper Resistance

This chapter explains how tamper resistance in single-player games begins with strong architectural design rather than isolated security techniques. It discusses how Unreal Engine’s predictable memory layout, reflection system, exposed properties, and object structures can make gameplay values easier for attackers to locate and modify. The chapter emphasizes key design principles such as minimizing attack surfaces, breaking up critical state, using redundancy, cross-validating systems, and introducing controlled unpredictability. It also highlights common developer mistakes, including exposing sensitive variables to Blueprints, storing important values together, and leaving debug tools in final builds. Overall, the chapter shows that secure architecture makes cheating harder, reduces reliable trainer creation, and protects progression, pacing, and gameplay integrity.
