Before You Dive In
Neon Abyss 2 is Veewo Games' cyber-mythic action roguelike: side-view run-and-gun combat, uncapped item synergies, the Hatchmon pet system, and the Faith system, with online co-op for up to four players. It entered Steam Early Access on 2025-07-17 and hit 1.0 on 2026-10-08 across PC, PS5, Xbox Series X|S, and Nintendo Switch. The core loop of any roguelike is "every run makes you stronger" — these fifteen tips will help you survive long enough to actually feel that progression.
The one rule above all
Scout first, spend second. The vast majority of early-run mistakes come from burning a key or a crystal before you've seen what the floor actually offers.
Weapons & Combat
1. Vaporize weapons you don't like — never force a bad one
Your starting weapon hits like a wet noodle, and the floor won't always hand you an upgrade. When you find a weapon that feels bad, hold the interact key to Vaporize it into Soul Shards and feed every shard into your main weapon's level.
Why: Each weapon level raises damage and triggers a choice between a Badge- or Artifact-type Curio. Badges add riders to your attacks (bouncing blades, extra projectiles, and similar effects), they stack, and — critically — they transfer automatically when you switch weapons. Vaporizing junk turns scrap into permanent build value for the run and chips away at weapon-related unlock tasks at the same time.
2. Don't get attached — switching weapons costs you nothing
When a weapon finally clicks for you, equip it immediately.
Why: Every Badge and Artifact you've earned on the old weapon moves to the new one automatically. Nothing is lost. The real risk isn't "switching is wasteful" — it's clinging to a mediocre maxed weapon so long that your scaling falls behind the enemies'. See the weapons system for the full breakdown.
3. Don't sleep on melee weapons
Neon Abyss 2 adds a large roster of melee weapons, and many of them produce ranged or AoE effects when boosted by the right items — some outright out-dps pure ranged builds in the right rooms.
Why: Melee trades reach for coverage and forgiveness: the hit box wraps around your body, so clean dodging converts directly into uptime. During your first hours, give any melee pickup a room or two of honest testing before you Vaporize it. Don't default to "guns are my real weapon."
4. Cheap shop weapons are the best gold sink in the game
The shop always stocks at least three items. When you see a weapon priced around 10 coins, buy it, equip it, and Vaporize it.
Why: A cheap weapon is a few coins converted into a pile of Soul Shards. Swapping through three weapons in one run feeds weapon-mastery unlock tasks and recycles the shards into your main weapon — the fastest early-game scaling loop there is. You can also expand the shop's stock slots later through the Evolution tree.
Resources & the Map
5. Plan your crystals, keys, and bombs before spending any of them
| Resource | Main uses |
|---|---|
| Crystals | Shop doors, special-room doors, crystal chests, activating Oddities, repairing gambling machines |
| Keys | Locked doors, key chests |
| Bombs | Breaking rocks and hidden passages |
| Coins | Shop purchases, repairing machines, converting Hatchmon colors |
Why: Everything is scarce early. Crystals that would exceed your carry cap can simply be left on the floor — as long as you haven't killed the floor's boss, you can come back for them. Clear most of the floor first and confirm where the shop, crystal chests, and Oddities are before committing resources. Repairing a gambling machine with crystals is usually better value than buying a low-tier weapon: the machine can pay out big, while the weapon was headed for the Vaporizer anyway.
6. Never shoot a chest
Any hit — a bullet or a bomb — on a crystal chest converts it into a Heart Chest, which costs a flat 1 heart to open instead of crystals. Hatchmon attacks are the one exception.
Why: The conversion is one-way. Triggering it at low health forces an awful choice between skipping the chest and walking into the boss room with an empty health bar. If you want the conversion (say, you're drowning in hearts but short on crystals), confirm your healing options first.
7. Be greedy on floors 1–4, cautious from floor 5
Why: Your combined cap is 12 hearts + shields. On floors 1–4 every hit costs only half a heart, so the game is explicitly telling you to poke into hidden rooms and take risky fights. From floor 5 onward, every hit costs a full heart — the same mistake is punished twice as hard. And remember: difficulty can be changed at any time from the bar, and it does not affect item drops. Don't white-knuckle a difficulty that's killing you.
Faith & Hatchmon
8. Pick low-commitment Faiths early; never switch at low health
Each floor starts at a stone pillar where you choose a Faith. Filling the Faith bar opens that Faith's temple for its reward.
| Phase | Recommended direction | Reason |
|---|---|---|
| Early floors | Artisanism, Fortunism (the gambling-themed Faith) | Built around weapon growth and high-variance payoffs; easy to progress |
| Mid-to-late run | Consumerism, Agapeism | Need steady coin, hatching, and key income to feed them |
Why: From floor 2 onward, switching Faith deals damage to you. Swapping below half health is one of the most common ways new players die to nothing. And a temple opening is not a summons — keep clearing the floor, stockpile the relevant resource, then cash in for a bigger payout. Faith interacts heavily with your weapon and Hatchmon build; see the Faith system.
9. Top off your Faith bar before the boss door
Before entering the boss room, prioritize combat rooms and events that push the bar to full and claim the temple reward.
Why: The temple is where a floor's Faith investment actually pays out. Walking into a boss with a nearly full bar is leaving a floor of progress on the table. Conversely, if the floor is going badly, it's entirely legitimate to bank the progress and cash it in on the next map instead.
10. Hatch eggs early and fuse low-tier Hatchmon — don't hoard
Hatched Hatchmon fight alongside you automatically; if one gets knocked out, touch it to wake it back up. Two same-tier Hatchmon fuse into a stronger Super Hatchmon.
Why: Hatchmon are power that grows while you do literally nothing — a mature stack can out-damage your own weapon, so earlier is always better. The efficient play is fusing two tier-1 Hatchmon into an egg: the hatch success rate is high, and it ticks off Apprentice/Master-level hatching tasks. Don't sit on low-tier Hatchmon cluttering your roster — fuse them. Some floors have a Hatchmon conversion machine that lets you pay coins to change a specific color, which enables targeted fusing. Grab any Oddity that raises your per-run fusion count (incubator-accelerator types). Full mechanics in the Hatchmon guide.
11. Plan each run around your unlock tasks
Per-run tasks are tied directly to weapon unlocks, and they're worth playing toward.
Why: Typical objectives read like "own 4 Hatchmon in one run," "use 5 bombs in one run," or "switch weapons 3 times in one run." Completing them unlocks new weapons and affixes — leverage that makes every future run stronger. Glance at the task list before entering the Abyss and let one or two convenient objectives steer your route.
Meta Progression & Co-op
12. Spend Evolution Points the moment you get them
Evolution Points earned at the end of each run unlock nodes on the Evolution tree — extra shop slots, stronger starts, and more.
Why: This growth is cumulative across runs; points sitting unspent earn nothing. Prioritize nodes you cash in on every run — shop slots and starting resources — because each one pays dividends from the moment it's unlocked.
13. Difficulty doesn't change drops — turn it down if you're stuck
During your first hours, set difficulty wherever the game feels comfortable, grind out unlock tasks and Evolution Points, then climb.
Why: Higher difficulties mainly scale enemy strength and Fate-system pressure, not the quality of item drops. Clearing unlocks on an easier setting is far more efficient than banging your head on a hard one. The bar lets you change it anytime with zero sunk cost.
14. In four-player co-op, divide the labor
Online co-op supports up to four players.
Why: Enemy HP and on-screen chaos scale up with headcount, so four people stacking the same route and fighting over the same pickups is the least efficient way to play. Before descending, roughly split duties: one player scouts for shops and temples, one babysits Hatchmon and triggers mechanisms, the rest focus on damage. Split keys and crystals on a "whoever needs it, takes it" basis — don't let one player burn the group's keys on their own chest.
15. In co-op, split Faith and Hatchmon duties between players
In multiplayer, have one teammate own hatching and fusing Hatchmon while another stacks Consumerism and pumps coins into the Faith bar.
Why: Both Hatchmon fusion and Faith progression demand attention, and one player juggling both usually fumbles both. Splitting the lines means the team ends up with high-tier Super Hatchmon and consistent temple payouts — co-op efficiency that solo play simply can't match. More in co-op.
Common Run-Killers: Quick Reference
| Situation | Correct play |
|---|---|
| Found a weapon that feels bad | Hold to Vaporize, feed the shards to your main weapon |
| Crystals near cap, still exploring | Leave the surplus on the floor, pick it up before the boss |
| Shop rolls a cheap weapon | Buy → equip → Vaporize for shards and task progress |
| Temple just opened | Clear the floor, stockpile resources, then claim |
| Half health and tempted to switch Faith | Don't — find healing first |
| Teammate is building Hatchmon | Leave same-color eggs for their targeted fusions |
| Reached floor 5 | Tighten up: fewer hidden-room gambles, play steady |
