Tips and Tricks
- S Rank Strategy: To achieve S ranks, focus on completing stages as quickly as possible and with minimal damage. Save at least one boost for critical sections of the level to maximize your speed.
- No Damage Bosses: For the “Untouchable” and “Can’t Touch This” achievements, patience is key. Learn the boss’s attack patterns, and don’t rush. Use Classic Sonic to handle smaller obstacles, and switch to Modern Sonic for easier mobility.
- Chao and Collection Boxes: Keep track of the Chao and boxes you’ve collected using the Collection Room. If you’re missing any, revisit earlier stages and explore alternate routes.
- Unlocking Skills: Some of the most useful skills for difficult challenges only unlock after you complete certain Red Ring sets or Challenge Acts. Make sure to visit Omochao’s Skill Shop often.
Conclusion
That wraps up our guide for Sonic X Shadow Generations achievements! With persistence and attention to detail, you’ll be able to grab every achievement in both the Sonic and Shadow campaigns. Whether you’re speeding through levels or hunting down hidden collectibles, there’s plenty to keep you busy. Good luck, and make the Ultimate Life Form proud!
