For completionists and trophy hunters, Sonic Forces offers a set of achievements/trophies that challenge you to master every aspect of the game. These range from story progression milestones to skill-based feats and extensive collection tasks. Earning all achievements requires dedication, replayability, and a thorough understanding of the game's mechanics. This section provides an overview of the types of achievements and general strategies for unlocking them.

Types of Achievements:
- Story Progression: Automatically unlocked as you complete main story stages and defeat bosses.
- S-Rank Achievements: Awarded for achieving an S-Rank on a certain number of stages, or all stages.
- Collectible Achievements: Unlocked for finding all Red Star Rings in a specific number of stages, or all stages.
- Avatar Customization: Awarded for unlocking a certain number of clothing items, or all items.
- Wispon Mastery: May involve using specific Wispons a certain number of times or completing stages with all Wispon types.
- Mission Completion: Unlocked for completing a certain number of Extra, Daily, or SOS Missions.
- Combat Achievements: May involve defeating a certain number of enemies, performing specific combat maneuvers, or defeating bosses without taking damage.
- Time-Based Achievements: Completing stages within very strict time limits.
General Strategies for Achievement Hunting:
- Complete Story First: Focus on finishing the main story to unlock all stages, characters, and basic Wispons.
- Prioritize S-Ranks: Work on S-Ranks for each stage. This will naturally lead to better times, more rings, and less damage, contributing to other achievements.
- Collect Everything: Actively search for Red Star Rings and other collectibles. This often requires replaying stages with different characters/Wispons.
- Engage with Side Content: Regularly complete Extra, Daily, and SOS Missions to unlock new Avatar customization items and potentially Wispons.
- Experiment with Avatars: Create multiple Avatars with different species and Wispons to tackle specific challenges or achievements.
- Practice & Patience: Some achievements are skill-based and will require multiple attempts and refinement of your gameplay.
- Check Achievement Lists: Refer to the in-game achievement list or an online guide to track your progress and plan your hunting strategy.
Earning all achievements in Sonic Forces is a rewarding journey that showcases your complete mastery of the game. It encourages you to explore every facet of the experience and push your skills to their limits.
Much like the team-up mechanics found in Sonic Advance 3, certain achievements in Sonic Forces require players to master specific character combinations to maximize their stage rankings.
While Sonic Forces rewards players for high-speed completion, its trophy list lacks the strict, no-damage boss requirements found in the classic achievements of Sonic the Hedgehog 2.
