Design risks
| R1 | Compulsion-loop pressure | 0.20 | |
| R2 | Monetization | 0.00 | |
| R3 | Social risk | 0.00 | |
The game features intense violence and horror elements due to the alien virus and mutated beings, which might be disturbing for younger audiences. The progression system and combat rewards could mildly contribute to compulsion-loop design.

- DSA:What Ludograph checks: whether the game's design gives minors the transparency the EU Digital Services Act expects: plain terms, honest defaults, and clear reporting routes.: Estimated from review data. No dark pattern or child-targeting concerns found.
- GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.: Estimated from review data. No privacy or child-targeting concerns found.
- ODDS:What Ludograph checks: whether paid random-reward drop rates are disclosed, as required in China, Japan and South Korea.: Estimated from review data. No paid random-reward mechanics found, so drop-rate disclosure requirements do not apply.
