How to play Last Bastion

Quick start — your first run

• Sign in with OMEN (one tap — no password, no seed phrase) and hit PLAY. Your first campaign mission is free, like every campaign mission after it.
• The Omen Core is the glowing heart at the center. Rift forces breach from the purple gates and march down the corrupted lanes toward it. If the Core's HP hits zero, the run ends.
• Pick a turret from the COMMAND dock (or press 1–5) and click open plating between lanes to build it. Shift-click places several in a row.
• Press SPACE (or LAUNCH) to send the wave. Kills pay Salvage ◈; cleared waves pay Energy ⚡ for more construction.
• Every few waves you'll draft one of three upgrades — exact stat changes shown on each card. This is where runs are won.
• Survive, expand, adapt. When the run ends you bank Shards ◇ for permanent upgrades — every run pays, win or lose.

Reading the battlefield

The Bastion is a ringed fortress. Enemies path inward along lanes; you build in the plating between them. The wave strip along the top previews exactly what's coming next — armor, speed, fliers, bosses — so you can rebuild your line before it's tested.

The five turrets

Every turret upgrades through six Mk levels (damage ×1.6 per level) and supports three targeting modes — first (default), strongest, and closest. Tap a placed turret to upgrade, retarget, or salvage it.

Battle spells

Equip three spells per run (competitive runs choose them at run start) and cast with Q W E or the spell bar. Every cast costs Energy ⚡ — there are no free spells — so a cast is always a trade against construction. Each spell has six upgrade levels.

Drafts — where runs are won

Every few waves — and after elites, bosses and ring unlocks — the run pauses and deals you three upgrade cards; you keep one. Cards show exact stat changes before you pick: turret damage, fire rate, range, Core armor, Energy income, spell power and rarer hybrid effects.

Expanding the Bastion

When you can afford it, EXPAND THE BASTION. Each new ring pushes enemy spawn gates farther from the Core, opens fresh buildable plating, and introduces one new pathing mechanic. Your old towers become the hardened inner line — expansion is how a good run becomes a deep one.

The five currencies

Every purchase in the game shows separate buttons per currency — the game only ever spends the one you tap. There is no automatic switching, ever.

CURRENCY	EARNED / SOURCED	SPENT ON	PERSISTS?
⚡ Energy	Clearing waves in-run	Turrets, upgrades, rings, spell casts	No — resets each run
◈ Salvage	Kills and waves in-run	Tactical supplies, rerolls, repairs	No — resets each run
◇ Shards	Every run, free, win or lose	Permanent upgrades (free lane)	Yes
OMEN	Your live OMEN wallet	Tournament entries, optional purchases, Perk Lab standard path	Yes — real balance
GMT	Your live OMEN wallet	GMT competitions & Prime path (rolling out)	Yes — real balance

OMEN and GMT are your real balances, read live from your authenticated OMEN account. The game never simulates them, and top-ups happen on the OMEN platform — never inside the game.

The Perk Lab — permanent power

Between runs, the Perk Lab converts your currencies into permanent account upgrades across eight tracks:

Each track has two paid paths — OMEN Standard and GMT Prime (stronger per level) — plus the free Shard lane. All purchases are server-authoritative and tied to your account, not your device.

The Campaign — 10 warzones, free forever

The campaign spans missions across 10 warzones, each with its own districts, environments and unlock chain. Missions gate new turrets (unlocks are shown on each dock button), open new districts, and pay Shards for the Perk Lab. There is no entry cost anywhere in the campaign — it's both the game and the training ground where permanent progression fully applies.

Ranked Campaign — the weekly ladder

• Free to enter. Seasons run weekly; everyone plays the same server-issued Bastion.
• Up to 3 runs per day — your best run each day is added to your season total. Consistency climbs the board, not one lucky spike.
• The account-power league: your permanent Perk Lab upgrades (and in-run purchases) apply here — ranked measures the strongest Bastion your account can field. Everyone still plays the identical server-issued map and seed.
• Free practice: take a practice run on the exact ranked Bastion first — nothing charged, no score submitted.
• When a run ends, your score is validated and banked server-side. Interrupted runs resume where they left off.
• Ladders pay the top of the board in prize currency when the season settles.

Tournaments — OMEN & GMT

• Run on daily, weekly and monthly cadences in both OMEN and GMT lanes, across stake divisions.
• Standard loadouts: permanent perks are disabled in tournaments (and War) — the bracket is pure skill on equal footing.
• Entry fee and full payout structure are shown before you enter. Your best score during the window ranks.
• Want another shot? Re-entry is offered at a reduced fee, with attempt limits displayed up front.
• At close, the event locks, ranks and settles automatically — no waiting on a human to declare winners.
• Same fairness engine as ranked: server-issued seeds, server-validated scores.

Prizes, payouts & trust

• Winners are paid in the competition's own currency — OMEN events pay , GMT events pay — once the event locks and settles.
• OMEN payouts are delivered on-chain to your OMEN account, visible in your history with the transaction record.
• Client scores never settle money. Only server-validated runs rank or pay.
• Your balances, entries and payout history are always readable in-game from authenticated server records.
