THE GAME

A run, in sixty seconds

The Omen Core sits at the center of the Bastion. Rift forces breach from the gates and push down corrupted lanes toward it. Your job: make sure nothing gets there.

⚙
DEPLOY

Build your line

Spend Energy ⚡ to place turrets in the open plating between lanes. Position is everything — chokepoints, overlapping ranges, slow fields feeding kill zones.

☠
HOLD

Survive the waves

Grunts, Stingers, armored Bulwarks, self-healing Wardens, flying Wraiths, the RIFT COLOSSUS — and from Mission 161, six Tier 2 archetypes that rewrite the rules. The strip up top previews what's coming.

Every few waves you draft one of three upgrades with exact stat changes shown. Stack Gravity with Explosive and watch entire waves disappear.

Rings unlock on schedule — up to 25 defensive rings by the final chapter. Each ring adds fresh pathing and pushes spawns farther out; your old towers become the hardened inner line.

THE ARSENAL

THE RIFT

Twelve archetypes. Three hazards.

The first six teach you the game. The Tier 2 six — from Mission 161 in the Campaign and every Ranked week from the W37 season — punish the line you built for the first six.

TIER 1GRUNTFodder that becomes a flood.
TIER 1STINGERFast. Slips a thin line.
TIER 1BULWARKArmored column. Lance food.
TIER 1WARDENSelf-heals unless you burst it.
TIER 1WRAITHFlies over your ground line.
TIER 1RIFT COLOSSUSThe boss. Everything at once.
TIER 2RIFTBORNIts death tears the Rift — allies crossing move +45% faster.
TIER 2LEECHSiphons 2 Energy/s from you while it lives.
TIER 2IRON HERALDAllies within its aura carry +30% armor.
TIER 2ADAPTIVE HUSKEvery turret class that hits it gains resistance.
TIER 2JUGGERNAUTSpeed climbs while unhit. Any hit resets it.
TIER 2RIFT ANCHORImmune to slows and stuns. Raw damage only.
HAZARD

≋ Rift Current

A ring band where enemies move +35% faster. Kill them before it — never rely on a choke inside it.

HAZARD

☁ Ion Fog

A ring band where turrets standing inside it lose 25% range. Build on either side of it, not in it.

HAZARD

⚡ Rift Storm

Every ~12s lightning marks an occupied pad, then strikes 2s later — that turret is silenced for 1.5s. Spread your damage.

Hazards appear in the Campaign after Mission 10 and one rotates into every Ranked week. Full intel on all twelve archetypes and the hazards is in the Field Manual.

WAYS TO PLAY

REAL STAKES · REAL PROOF

Winners get paid.

Prize pools are real OMEN OMEN. Payouts aren't a promise on a roadmap — settlement is automatic and winners are paid in the competition's own currency once each event locks.

REAL PRIZE POOLS

OMEN payouts

Entry costs, attempt limits and full payout structures are shown in-game before you enter. No surprises, no fine print after the fact.

PROVABLY FAIR

Client scores never settle money

Every competitive run plays on a server-issued seed and must pass server validation before it can rank or pay. Every mode plays the same server-issued map for everyone in it.

YOUR IDENTITY

One OMEN account

Live balances, entries, histories and payouts are read from authenticated server records — never browser-local values. Sign in once, play everywhere.

NEVER LOSE A RUN

Disconnect protection

Runs checkpoint as you play. Lose power mid-wave and you resume right where the line held — turrets, perks and score intact.

Beta: features and rewards may change. No financial returns are guaranteed. Last Bastion never requests your seed phrase, private key, Discord password or a direct wallet signature.
FAQ

Quick answers

Is it actually free?
Yes. The full campaign is free forever, and Shards ◇ — the currency behind every permanent upgrade — are earned only by playing. The Ranked Campaign is also free to enter. Tournaments carry an entry fee in OMEN, always shown before you commit.
Do I need a crypto wallet to play?
No. You sign in with a one-tap OMEN account — no password, no seed phrase, no wallet signature. Your OMEN identity carries balances and rewards when you're ready for competitive play.
Where do permanent upgrades count?
In the free Campaign and the Ranked Campaign — ranked is the account-power league, where the strength you've built (free Shard lane or paid paths) competes on the identical server-issued map, and your paid OMEN path stacks with your free Shard lane. The same is true of Tournaments, Leagues and the Monthly War — permanent power applies everywhere, on the same server-issued map for everyone. Every score in every lane must pass server validation.
How do prize payouts work?
When an event closes, the server freezes scores, ranks entries and settles automatically. Winners are paid in the competition's own currency (OMEN OMEN) once the event locks and settles. Payout structures are published in-game before entry.
What are Tier 2 archetypes and hazards?
Six new enemy types that each break a habit — a Leech that drains your Energy, a Husk that adapts to whichever turret keeps hitting it, an Anchor that ignores slows. They arrive from Mission 161 in the Campaign and in every Ranked week from the W37 season. Hazards (Rift Current, Ion Fog, Rift Storm) change the field itself. The Field Manual has the full intel.
What happens if I disconnect mid-run?
Runs checkpoint continuously. Reopen the game and you'll resume exactly where you left off — turrets, drafted perks, wave and score intact. Competitive runs are protected server-side too.
Can I try a ranked run without risking anything?
Yes — open the Ranked Campaign and take a free practice run on the exact ranked Bastion. Nothing is charged and no score is submitted. The ranked ladder itself is also free to enter.
What is OMEN ?
The OMEN platform's currency. Your balance is read live from your authenticated OMEN account — the game never simulates it. It funds tournament entries and optional purchases, and prize pools pay out in it.
How is cheating prevented?
The game is server-authoritative: competitive runs play on server-issued seeds, and every score must pass server validation before it can rank or pay. A client can't invent a score that settles money.
