QA – Delivers Flawless Player Experiences

Make your localized game feel native in every market with our in-depth linguistic and gameplay QA.

MarsHub’s Game Localization QA Services

Linguistic QA

Check translations for grammar, spelling, tone, context, and consistency with your game’s narrative and style.

In-Context Review

Validate translations directly inside the game interface to catch issues that only appear during live gameplay.

Cultural Sensitivity Checks

Ensure all content aligns with regional norms, humor, and sensitivities, avoiding offense or confusion.

UI/UX Localization Testing

Identify layout issues, such as text overflow, font rendering errors, misaligned elements, or broken characters.

Voice & Subtitle Sync QA

Match localized voiceovers and subtitles with accurate timing and visual placement, which is critical for cutscenes and narratives.

Platform-Specific QA

Test localized builds across platforms (PC, console, mobile) to make sure language-specific elements render properly everywhere.
