Achievement Guide & Checklist
Unlock every One Turn Kill achievement with a practical checklist, completion rates, boss targets, and tips for 50-card turns and 150-damage hits.
Achievement List at a Glance
One Turn Kill achievements reward you for pushing a single run further than most players bother to go. If you have cleared the main path, the remaining One Turn Kill achievements are where the real checklist begins: single-turn kills, massive attacks, boss wins, and deck-wide upgrades. This guide turns the achievement list into a practical route, with completion signals, hidden targets, and focused tips for the grind.
The game has 18 achievements: 10 visible goals and 8 hidden ones. The visible set covers basic milestones, while the hidden set leans on story battles and optional challenges. Completion rates range from nearly universal to under one in five players, so use them as a priority map rather than a skill score.
| Visible achievement | Requirement | Approx. completion | Priority |
|---|---|---|---|
| One-Turn Kill | Defeat an enemy in a single turn | 98–100% | Very high |
| Power Up | Upgrade a card | 55–63% | High |
| Tireless | Use a total of 500 cards | 55–61% | Passive |
| Card Collector | Unlock all cards | 40–44% | Medium |
| Game Completed | Complete the game | ~35% | Medium |
| Overkill | Inflict 150 or higher damage with one attack | 22–24% | Build-specific |
| Route 98 | Use Laevatein with the effects of Homeward Bound | 21–24% | Combo-specific |
| Perpetual Motion Machine | Use more than 50 cards in a single turn | 19–22% | Build-specific |
| Gadget Junkie | Upgrade all cards | 17–22% | Long-term |
| Orbit | Activate five Procyon Devices | 17–23% | Route-specific |
One-Turn Kill is the closest thing to a free achievement; it asks for a single-turn victory and shows up for nearly every player. Power Up and Tireless are the next natural stops. The One Turn Kill achievements near the bottom of the table—Gadget Junkie, Orbit, and Perpetual Motion Machine—ask for dedicated runs or long-term cleanup.
Fastest Achievements to Knock Out First
Start with goals that happen during normal play. The easiest One Turn Kill achievements do not need a special build; they need a little attention so you do not finish a run and realize you skipped them. Knock out the simple combat and upgrade milestones before you start chasing specific combos.
| Priority | Achievement | Requirement | Why do it early |
|---|---|---|---|
| 1 | One-Turn Kill | Defeat an enemy in a single turn | Almost automatic; 98–100% |
| 2 | Power Up | Upgrade a card | Simple first upgrade |
| 3 | Practice battle with Rita | Have a practice battle with Rita | Early hidden check; ~51% |
| 4 | Defeat the scarecrow | Defeat the scarecrow | Hidden objective; ~25% |
| 5 | Tireless | Use a total of 500 cards | Builds passively; 55–61% |
| 6 | Card Collector | Unlock all cards | Progresses over multiple runs; 40–44% |
Do the practice battle with Rita early because it is a low-pressure hidden objective. Defeat the scarecrow when you want a break from the boss route. Let Tireless and Card Collector build in the background as you chase other goals. If you focus only on the hardest achievements first, you may finish them and still need a cleanup run for the basic ones.
Boss and Hidden Targets
The hidden side of the One Turn Kill achievements is mostly about named fights. The BIAS 5 bosses are Captain, Azwen, D-rex, Bulk, and Pastor; tracked completion drops from Captain to Pastor. Rita appears in two separate goals: a practice battle and a BIAS 20 checkpoint. The scarecrow is a standalone hidden target.
| Hidden objective | Type | Approx. completion | Focus |
|---|---|---|---|
| Have a practice battle with Rita | NPC battle | ~51% | Do it early |
| Defeat BIAS 5 Captain | Boss | ~40% | First BIAS 5 target |
| Defeat BIAS 5 Azwen | Boss | ~39% | Continue the boss route |
| Defeat BIAS 5 D-rex | Boss | ~33% | Mid-route check |
| Defeat BIAS 5 Bulk | Boss | ~31% | Later boss |
| Defeat BIAS 5 Pastor | Boss | ~28% | Deepest boss |
| Reach Rita with a total BIAS of 20 | Progression | ~29% | Track BIAS total |
| Defeat the scarecrow | Optional fight | ~25% | Detour objective |
Treat each hidden objective as a route marker. If you are already fighting through the BIAS 5 list, check your hidden achievements after each win. The practice battle with Rita and the scarecrow are easy to postpone, so clear them before they become cleanup chores. The BIAS 20 checkpoint also gives you a reason to watch your total instead of rushing from fight to fight.
How to Clear the 50-Card and 150-Damage Challenges
These are the two most build-sensitive One Turn Kill achievements. Perpetual Motion Machine wants volume; Overkill wants one huge hit. Trying to force both in the same turn usually leads to an early kill and a missed count.
| Achievement | Requirement | Setup principle | Watch out for |
|---|---|---|---|
| Perpetual Motion Machine | Use more than 50 cards in a single turn | Build a turn around low-cost cards and repeatable card play | Killing the enemy before you reach 50 |
| Overkill | Inflict 150 or higher damage with one attack | Save your strongest single-hit setup for one target | Splitting damage across several attacks |
| Route 98 | Use Laevatein with the effects of Homeward Bound | Activate Homeward Bound first, then use Laevatein | Using Laevatein before the effect is active |
| Orbit | Activate five Procyon Devices | Spread device activations across a run | Losing count or ending the run early |
For Perpetual Motion Machine, hold back lethal damage until you have played more than 50 cards. Build the turn around cards that keep your hand full and your plays cheap. For Overkill, do the opposite: save your strongest single-attack setup and unleash it on a target that can survive the setup turns. Route 98 and Orbit are separate combo goals, so give each one its own run. If you mix them with a boss attempt, you may satisfy one condition and miss the other.
Upgrade, Unlock, and Completion Checklist
The cleanup phase is where the remaining One Turn Kill achievements live. Gadget Junkie asks you to upgrade every card, while Card Collector asks you to unlock every card. Pair them: as new cards arrive, upgrade them before moving on. That prevents a last-minute sweep through the whole collection.
| Checkpoint | Achievements | Action | Tracking tip |
|---|---|---|---|
| First run | One-Turn Kill, Power Up | Win a battle in one turn; upgrade a card | Do this before experimenting |
| Early hidden | Practice battle with Rita, Defeat the scarecrow | Clear both hidden objectives | Check the hidden list after each run |
| Boss route | BIAS 5 Captain through Pastor | Defeat all five bosses | Move to the next boss after each win |
| BIAS check | Reach Rita with total BIAS of 20 | Build toward the BIAS threshold | Verify before ending the run |
| Combo run | Route 98, Orbit | Use Laevatein with Homeward Bound; activate five Procyon Devices | Do one combo goal per run |
| Big turn | Perpetual Motion Machine | Play more than 50 cards in one turn | Hold lethal damage |
| Big hit | Overkill | Deal 150 or higher damage with one attack | Focus setup on one hit |
| Collection | Card Collector, Gadget Junkie | Unlock all cards; upgrade all cards | Upgrade new cards as they arrive |
| Cumulative | Tireless, Game Completed | Use 500 cards; finish the game | Let these fill in naturally |
Tireless and Game Completed can fill in while you work on other goals. One-Turn Kill and Power Up should already be done by the time you start this checklist. If you are missing either, run a simple battle and upgrade any card before returning to the grind. The goal is to avoid reaching the end with a scattered list of easy tasks.
A Practical Order for One Turn Kill Achievements
A clean order reduces backtracking. Use this sequence as a flexible plan, not a strict law. If a run naturally offers a boss or combo goal, take it.
- Clear One-Turn Kill and Power Up in your first serious run.
- Do the practice battle with Rita and defeat the scarecrow while your deck is simple.
- Work through the BIAS 5 bosses from Captain to Pastor.
- Reach Rita with total BIAS of 20 on a run where you are tracking progress.
- Build dedicated turns for Perpetual Motion Machine, Overkill, Route 98, and Orbit.
- Finish Card Collector, Gadget Junkie, Tireless, and Game Completed.
Track your One Turn Kill achievements after each session. The hidden list is the easiest place to lose progress, especially if you forget whether you defeated the scarecrow or activated enough Procyon Devices. A short checklist saves a long cleanup run. If a goal feels stuck, switch to a different achievement and come back with a deck built for that single task.
One Turn Kill Achievement FAQ
How many One Turn Kill achievements are there?
There are 18 total: 10 visible achievements and 8 hidden achievements. The visible list covers one-turn kills, upgrades, collection goals, and damage thresholds. The hidden list includes Rita, the BIAS 5 bosses, the BIAS 20 checkpoint, and the scarecrow.
Which One Turn Kill achievements have the lowest completion rates?
Gadget Junkie and Orbit sit in the lowest band, around 17–23%. Route 98 and Perpetual Motion Machine are close behind. Low rates often reflect extra setup or long-term grind rather than raw combat difficulty, so do not assume they are impossible.
Can I earn all One Turn Kill achievements in a single run?
Unlikely. Cumulative goals like Tireless and collection goals like Card Collector span multiple runs, and the 50-card turn and 150-damage attack pull your deck in different directions. Plan separate runs for the big turn, the big hit, the specific combo, and the boss route.
How do I unlock the hidden One Turn Kill achievements?
Complete the hidden objectives: have a practice battle with Rita, defeat each BIAS 5 boss, reach Rita with a total BIAS of 20, and defeat the scarecrow. Check the hidden list after major fights so you know which target is still missing.
