How to play
Create an account or play as a guest, take the personality test to find your partner, and head
into the dungeon.
| Key | Action |
|---|
W A S D / arrow keys | Move |
1 2 3 4 | Pick the active move |
Q / E | Cycle moves |
F (Y on a controller) | Pull the markers for things off screen around your Pokémon |
Esc / P | Pause |
Controllers work too (Settings → Controls). On a phone or tablet (landscape), put your finger
anywhere and drag to move, tap a move at the bottom to switch to it, and use the button at the top
right to pause. The touch buttons can be moved anywhere. The game can be installed as an app ("Add
to Home Screen").
The game is in English. Spanish, French, Italian, Brazilian Portuguese and Chinese (Simplified
and Traditional) are in Settings → Graphics → Language.
The game
- 966 Pokémon from all 9 generations, with sprites from Pokémon Mystery Dungeon
(PMD SpriteCollab), original music and sound.
- Your Pokémon attacks on its own with its active move. Level-ups offer new moves, stat boosts
and items (Leftovers, Choice Band...), and moves evolve at their top level. Level-up cards
come in rarities, from Common (×1) to Legendary (×3).
- Rocks, chests and tall grass break; walls and trees block enemy shots; water slows you and lava
burns (enemies too). The map has power altars, healing springs, locked chests and traps.
- Rifts open now and then: step in to fight a legendary in its own arena. Each legendary you
beat gives a bond, which fuses up to 4 moves into one slot that casts them all at once.
- A type chart (a water move hurts a Charmander more) and weather (sun, rain, sand, snow,
fog) that boosts some types and weakens others.
- Enemies have personalities: some heal, shield, call their pack or warn before an area attack.
- Each wild Pokémon has a 1 in 4096 chance to be shiny. An arrow points to it, and beating it
makes it yours.
- At 30:00, the Eternatus raid begins; winning lets the run continue.
- Mega Evolution: past minute 5, a won rift can drop a Mega Stone, and holding it Mega Evolves
a Pokémon that has a Mega.
Between runs:
- Upgrades for each Pokémon. With every upgrade bought, prestige it: its upgrades reset
and its runs get +5% HP, damage, speed and damage cut per prestige level, up to 3; at 3 it
starts every run holding a random item.
- The gacha, pulled on a pixel-art slot machine with tickets won by playing (×1 from some
Pokémon, ×10 from bosses and legendaries). Each region has its own banner, and a Legendary is
guaranteed by pull 220 (more likely from pull 180). The Rainbow ×25 ticket gives 25 pulls
with at least one Legendary.
- Radiant forms: a third look after normal and shiny. The Radiant Ritual trades 10 of your
shinies for one radiant.
- Daily and weekly missions, achievements with medals and titles, and a profile with
your favourite Pokémon and records.
- Co-op for up to 4 players (add them by nickname, invite them to your lobby) and
leaderboards (solo or group, daily to all-time, by Pokémon). Co-op connects players
directly, peer to peer, so a few strict networks can't join.
All former Lab features are now standard gameplay, in solo and co-op: species learnsets and
abilities, signature moves, new move kinds, branching upgrades, set bonuses, synergies, bond
recipes and co-op support moves. Pokémon can evolve during a run, earn candy from duplicates,
complete contracts and spend gems. Runs offer revive cards, Overhealth and reload resume;
wild legendaries roam from 15:00, and rifts can contain Mega and Primal legendaries.
From 20:00, map sites offer guardian fights and relics. The Eternatus raid at 30:00 replaces
Arceus's Judgment; beat it to continue toward Necrozma at 45:00 and the growing endless horde.
Every new run counts for regular leaderboards, missions, achievements, personal records and
stats. Earlier Lab leaderboard entries remain under Lab archive. The old Lab toggle is retired.
Saves
With an account (name and password, or Google), your game is saved in the cloud and follows you to
any device. Unsaved progress is uploaded by itself, and when two devices played offline, their saves
merge: collections join (no Pokémon or shiny is ever lost) and upgrades and stats keep the higher
value. As a guest, progress stays in this browser and moves to your account when you sign up or
log in. A save from the original PokéSurvivor can be imported.
Development
HTML, CSS and vanilla JavaScript on Canvas 2D, no framework. The fork keeps upstream's code and
adds its own on top, so upstream's updates merge without conflicts:
node fork/build.cjs # build index.html, js/app.min.js and the site pages
node fork/sync.cjs # pull upstream's updates, rebuild, commit
python -m http.server 8123 # play at http://127.0.0.1:8123/
fork/README.md explains how the fork is built, what it changes and how each
part is tested; fork/LAB.md tracks Lab mode. English is the project's language:
new text in the game and the docs is written in English only.
