01Before your first run
Start a new game and play the tutorial. The developer added it in the Day 1 Update and recommends a fresh save so it is set up correctly for future patches.Day 1
- Since Hotfix 0.4.01, saves from incompatible older versions will not load. The game asks you to start a new game instead.0.4.01
- If you opt into Steam's public beta branch, your save may stop working on the stable release.Beta
- After a crash, the next launch shows a message with debug information. The developer asks players to screenshot it and post it on the Steam forums or the official Discord.Forum See crash fixes.
02How a run works
The Early Access version is a "roguelike tower". Procedural generation builds increasingly harder levels as you go, and a run can reach the final star cluster and beat the scenario.Steam You move between floors with Elevators, and boss fights are tied to them: since 0.4.026b, an elevator whose boss you have beaten will not spawn a new boss fight if you leave and come back.0.4.026b0.0291
Scenarios are chosen as programs. Completing the first program unlocks DEFRAG, and completing DEFRAG unlocks Death In Green.DEFRAGBeta
Coverage of the 2023 PAX demo described a plague-stricken captain who stays aboard ship and sends crew on expeditions, with a plague meter that ends the game when full.2023 preview That predates Early Access. The current store page describes a party exploring Atropos, so treat demo-era details as possibly out of date.
03Build your Order Deck
Combat is a turn-based card battle. Your cards are called orders, and your Order Deck is built from who you bring and what equipment they carry.Steam That means party choice is deck-building: each crew member and each item changes the cards you can play.
- Items change orders. The store page says powerful items "can change how orders play and interact".Steam
- Check your synergies. Manage Party → select a unit → Effects lists every card contributing effects to that unit.0.4.02
- Consumables count too. Since 0.4.026 you can use Field Inventory items during combat.DEFRAG
Before a boss, open Effects on each unit. It is the quickest way to see which cards an item has added to your deck, and to catch items that are not doing what you expected.
04Positioning & formation
Position matters: the game lets you use it to avoid attacks, gain buffs and out-manoeuvre enemies.Steam Your units sit in a formation with limited slots. Summons such as the Pirate Technic's Autocannon also need a free slot.0.4.02
- Pushing attacks move units. Since 0.4.029 they work correctly against enemies that take up more than one tile.0.4.029
- Some boss mechanics are positional. In the Nightmare Slurry fight, Slurp only hits targets standing in the bile pools.0.4.02 See the boss guide.
- Deployed summons such as Minibots take up formation space too. Leave a slot free if you plan to summon.0.4.020.4.024
05Skill tests
Outside combat, the game "challenges your crew" with skill tests.Studio You choose which crew member attempts the test, and a card sacrifice mode is part of the flow.0.4.02 In the 2023 demo, one example was a rock wall that a stronger crew member could get past.2023 preview
Pick the crew member whose role fits the challenge, and think about which cards you can spare before you commit. Sacrificed cards are cards you will not have for the next fight.
06XP, Boons & permanent upgrades
| System | What we know | Source |
|---|---|---|
| XP & levels | Manage Party's unit sidebar shows current XP and the XP needed for the next level. Defeating the Sentinel Program grants XP. | 0.4.02 |
| Boons | Run rewards. Completing an Assassination mission grants one. | 0.4.02 |
| Permanent upgrades | Improve your team's survivability and unlock build-defining abilities. | Steam |
| Minibot upgrades | Deployed Minibots can be upgraded into new types, and their HP rises with upgrades. | 0.4.0240.4.026 |
| Character mods | Rewards from Weapons Cache locations, added with DEFRAG. | 0.4.026 |
| New classes | Sidequests can unlock new items and classes. The Engineer is one class you unlock. | Steam0.4.02 |
07Grist, shops & loot
Grist is also the name of the in-game currency you spend on shopping and other expenses. With the Greensward update the developer removed the split between your total Grist and the Grist earned during a mission, so you can spend it more freely mid-mission.Beta
- Megamart shops sell weapons and consumables. Their stock grew in 0.4.026.DEFRAG
- Weapons Cache locations reward character mods.0.4.026
- Some enemies drop gear. Vandals can drop a Sling.0.4.02
- DEFRAG added more ammunition types, plus new items found by exploring, visiting shops and completing sidequests.0.4.026DEFRAG
08Route planning
You plot map routes yourself. The store page lists three reasons to take a detour: levelling, finding advanced weaponry, and sidequests that unlock new items and classes.Steam Steam tags the game as Hex Grid.Steam
Early in a run, prioritise detours that give XP and gear before the floor boss. Because levels get harder as you climb, an under-levelled party falls behind fast.
09First-run checklist
- Start a new game and finish the tutorial.
- Choose your party with the deck in mind. Crew and gear decide your orders.
- Keep a formation slot free if you plan to summon.
- Check Manage Party → Effects after picking up new gear.
- Spend Grist at Megamarts, and visit Weapons Caches for mods.
- Take sidequests that unlock classes and items.
- Read the boss notes before the first floor boss.
?Quick answers
Should I start a new game after updating Grist?
Yes. The developer recommends a new game to get the tutorial and a correctly set-up save, and since 0.4.01 saves from incompatible older versions will not load.
How is the Order Deck built in Grist?
Your Order Deck comes from your party: which crew members you bring and what equipment they carry. Items can change how orders play and interact.
How do I see what is affecting a unit?
Open Manage Party, select the unit and open Effects. Since 0.4.02 it lists every card contributing effects to that unit, and the sidebar shows current and required XP.
Can I use items during combat?
Yes. Since the DEFRAG update (0.4.026) items in your Field Inventory can be used during combat.
