- 385 achievements spread across GemCraft, Chapter 0, and Labyrinth in one Steam collection
- Phase your progress: campaign first, battle amulets second, endurance and challenges last
- Battle amulets unlock based on how you win a field, not just clearing it
- Respec skills before dedicated cleanup runs for endurance and high-difficulty goals
- Mark completed maps immediately so cleanup passes target unfinished objectives only
Achievement System Overview
GemCraft Legacy Collection launched on Steam on October 21, 2026, bundling three classic tower defense games with roughly 385 achievements and more than 100 hours of content. Achievements do not follow one universal rule set: each included game keeps its own progression, challenges, and unlock conditions, so planning matters more than grinding.
Video Highlights:
- The collection includes GemCraft: The Forgotten, Chapter Zero, and Labyrinth
- Over 100 hours of maps, skills, and challenge content
- Achievements are a headline feature of the Steam release
The table below breaks the achievement pool into practical categories:
| Category | What It Covers | Difficulty | Best Approach |
|---|---|---|---|
| Campaign progress | Clearing maps in each included game | Easy-Medium | Natural playthrough |
| Battle amulets | Win conditions like speed, kills, no-gem-loss | Medium | Dedicated builds per objective |
| Collection unlocks | Total maps, amulets, or wizard levels accumulated | Medium | Steady long-term play |
| Hidden and special | Hidden maps, unusual battle settings | Medium-Hard | Exploration and experimentation |
| Endurance and challenge | Extended waves, restrictive traits | Hard | Respec'd late-game build |
Do not assume unlocks carry over between GemCraft 1, Chapter 0, and Labyrinth. Each game in the collection retains its own achievement structure, and codes or progression from one chapter do not apply to the others.
Achievement Distribution by Game
Each part of the collection contributes a distinct slice of the 385 total. The exact per-game split has not been officially itemized, so treat the categories below as planning buckets rather than fixed counts.
| Game | Achievement Focus | Progression Style | Main Challenge Type |
|---|---|---|---|
| GemCraft: The Forgotten | Core campaign clears and basic amulets | Linear campaign | Learning fundamentals |
| Chapter Zero | Expanded campaign, skills, map progression | Larger progression system | Build specialization |
| Labyrinth | Map exploration, battle settings, endurance | Non-linear map network | Modifiers and endurance |
GemCraft: The Forgotten
- Best starting point
- Teaches placement, combining, targeting
- Straightforward achievement base
Chapter Zero
- Broader skill and map systems
- More collection-style unlocks
- Rewards consistent progression
Labyrinth
- Deepest challenge pool
- Battle settings alter every field
- Home of hardest endurance goals
Play GemCraft first to learn the rules, then Chapter Zero, then Labyrinth. This order means the hardest achievements come when your skills and game knowledge are strongest.
Step-by-Step Full Completion Route
A complete achievement route is easier when progression and cleanup are separated into deliberate phases.
Clear the campaigns naturally
Advance through each included game's campaign maps, unlocking fields, battle settings, and progression options as they appear. Avoid restarting for missed amulets during this phase.
Record what is already done
Mark completed maps and collected amulets immediately. Later cleanup runs should target unfinished objectives instead of repeating ordinary clears.
Sweep battle amulets
Replay cleared fields with builds matched to each objective: survival-focused setups for endurance goals, burst builds for speed clears, mana-stealing builds for resource targets.
Hunt hidden maps and special challenges
Inspect map progression for fields that break the normal route, and experiment with alternate battle settings when a field presents unusual unlock conditions.
Respec and finish endurance
Reset skills toward sustained damage, mana efficiency, armor counterplay, and crowd control, then complete the most demanding endurance and high-difficulty objectives in a dedicated pass.
Campaign clears naturally earn the easy majority of achievements. Cleaning up restrictive amulets afterward with a purpose-built save avoids wasted attempts and repeated respecs.
Battle Amulets and Objective Builds
Many completion goals are tied to how a battle is won rather than simply reaching the next map. Match your gem package to the objective before starting the final attempt.
| Objective Type | Recommended Gem Core | Support | Key Spell Timing |
|---|---|---|---|
| Speed clear | Direct damage, chain hit | Range amplifier | Spend early, keep tempo |
| Kill count | Splash and chain effects | Slowing gem in trap | Control before crowds reach exit |
| Survival waves | Scalable high-grade damage | Mana stealing | Cycle recovery and control |
| No losses | Slowing plus armor tearing | Backup safety tower | Save control for fast leaks |
| Resource goals | Mana-stealing gems | Poison for sustained output | Low-cost spells used frequently |
If your campaign build was not designed for a specific amulet, replay the map with a dedicated setup instead of forcing it with an unsuitable configuration.
Endurance and High-Difficulty Cleanup
The hardest achievements combine enemy scaling, restrictive traits, and long-term resource pressure. Follow this checklist before each endurance attempt:
Before an Endurance Run:
- Respec toward sustained damage, mana efficiency, and armor counterplay
- Build one scalable central kill zone instead of spreading early resources
- Keep a separate control or splash setup for swarms
- Plan the full spell cycle around boss and wave-overlap timing
- Confirm the field's battle traits and restrictions before committing
Overbuilding multiple towers before the main gem reaches a grade capable of handling scaling enemies is the most common reason endurance attempts collapse mid-battle.
FAQ
Q: How many achievements are in GemCraft Legacy Collection?
The Steam release features approximately 385 achievements spread across the three included games: GemCraft: The Forgotten, Chapter Zero, and Labyrinth, alongside more than 100 hours of content.
Q: Do achievements or unlocks carry over between the three games?
No. Each game keeps its own campaign, skills, and unlock structure. Progression completed in one chapter does not transfer as codes or unlocks into the others.
Q: What are battle amulets in the achievements guide?
Battle amulets are objectives tied to how you win a field, such as surviving extended waves, clearing quickly, reaching kill counts, or hitting resource targets. Many achievements require collecting them across multiple maps.
Q: Should I reset my skills for the hardest achievements?
A full respec is justified when moving from ordinary maps to endurance or challenge modes. Rebuild around sustained damage, mana efficiency, and crowd control rather than preserving an early-game generalist setup.
