Every menu. Every system. One field guide.

Samurai Task Force fights in a narrow strip above your Windows taskbar. You choose the squad, spend its resources and decide when to intervene. Combat continues on its own.

Samurai Task Force battle strip in Wood League
The live battle strip stays compact while its management windows open separately.

01 · First steps

Choose a fighter, then let the strip work.

Home window showing the active party and next steps

Start and control the game

  • Choose one starter fighter. The first squad starts with three fighters and can grow to four.
  • Drag the battle strip to move it. Resize it from the edge; management windows can also be moved and resized.
  • Open System for sound, performance, front-window behaviour, language and display controls.
  • Use Menu → Report a Bug. The form adds build and game-state information and can attach a screenshot.
  • When an update appears, choose Update now. If the automatic update cannot finish, use Download from website and run Setup once.

02 · Combat

Five leagues, eight waves, then a boss.

Progress and defeat

Wood, Iron, Silver, Gold and Master League each contain eight regular waves and one boss stage. On the first defeat at a stage, the party returns two waves; later defeats at the same stage return one wave. Gold and unassigned loot earned during that failed attempt are lost, while permanent upgrades remain.

Lives and revive

Each fighter has five lives. A fall can remove one life only once every 45 minutes. At zero lives the fighter is out. Home and Skills show the revive action. Revive restores health and lives.

Revive price ladder

The current league income sets the base. The base is at least 3,000 gold and equals 300 foes of the best reached league; Silver and above add 30%. Each use multiplies the price by 1.495, capped after four increases. Home shows all five current prices.

Mend, Ki and danger

Mend weakest fully heals the standing fighter missing the most HP for 45% of the group-heal price. Heal party restores 60% of maximum HP to every hurt standing fighter. Landed hits fill Ki; at full charge the next release uses the best available Power skill. The danger warning appears when projected damage threatens the party.

Offline progress

The game simulates up to eight hours away at 50% efficiency. Offline catch-up does not consume fighter lives. Online features such as rankings and bosses still need a connection.

03 · Home and Shop

Your overview and optional content.

Home overview with party, revive ladder and shortcuts
HomeChecks league, wave, record, party status, revive prices and recommended next actions. Quick Access opens the main management windows.
Shop window with bundle, hero, skin, music and extras tabs
ShopBrowse bundles, heroes, skins, music and extras; restore owned content or open the secure website purchase page. Holder benefits are account entitlements and can be restored here.

04 · Inventory

Compare first. Protect what you keep.

Inventory with filters, search, sold items, stash and materials
  • Filter by availability, rarity and type; search by type, grade or owner; sort the visible list.
  • Each fighter can carry one Blade, one Guard and one Charm. Choose a fighter to compare the exact result before equipping.
  • Lock prevents selling, storing, salvaging, converting and reforging until you unlock the piece.
  • Sell shown sells only filtered, unassigned, unlocked items. Equipped, protected and hidden items stay.
  • Sold keeps the last 20 sales. Buy back an item for its sale price.
  • Stash stores inactive pieces. They give no bonus and cannot be equipped until returned. Materials shows global equipment tiers and Harmony.

05 · Heroes, formation and Skills

Build a four-fighter formation.

Heroes window with formation slots, filters and fighter details
Heroes / ClanFilter unlocked, active and reserve fighters. Recruit with gold, deploy a reserve, choose who leaves the active party and inspect equipment or abilities. Three different classes grant 4% party damage; four grant 8%.
Skills and Training window with fighter ranks, upgrades and Ki slots
SkillsBuy permanent gold upgrades, spend earned training points and inspect Ki skill slots. Reserve fighters can be included. Healing restores current HP; it is not a permanent stat upgrade.

06 · Runes and progression

Spend earned points on lasting branches.

Progression window showing Fire, Frost, Lightning and Wind rune branches

Mastery uses account-wide points earned from fighter level-ups. Runes are per fighter: every two levels earns one element point.

Raise Fire, Frost, Lightning or Wind ranks to apply the listed effect. The right panel shows free points, active synergies and the next rank. Reset refunds that fighter's element points for the shown gold cost.

07 · Map and Journal

Revisit unlocked stages without losing progress.

World map with league chapters, stages and boss controls
MapInspect chapters, reached stages, first-clear rewards and the active fighter. Travel only to reached stages. Call the current league boss after reaching it once, or hold the boss so the party repeats the final regular wave.
Journal window with battle history and search
JournalSearch battle history and current goals. Use it to understand what the simulation completed while you were managing another window or away.

08 · Dojo

Five buildings strengthen the whole roster.

Dojo path with Hall, Forge, Shrine, Tea House and Gate
  • Forge: damage. Hall: XP. Tea House: health regeneration.
  • Shrine: critical chance. Gate: maximum health.
  • Each building can be raised independently to level 10. Honour increases the available building cap.
  • A fighter whose preferred building matches receives 1.5 times that building's per-level effect.

09 · Workshop

Seven modes, plus Convert inside Salvage.

Workshop with Upgrade, Synthesis, Engraving, Inscription, Decoration, Reforge and Salvage tabs

Upgrade

Improve a piece with gold. Assigned equipment stays with its fighter.

Synthesis

Consume three matching, unassigned pieces to create one item of the next grade.

Engraving

Inscription

Convert

Inside Salvage, change the type of a free, unlocked piece. Grade, effects, gems and engraving stay.

10 · Equipment Sets and Market

Save loadouts; separate local sales from online trading.

Equipment Sets window with three saved loadout slots

MarketSell unlocked, unassigned gear to the local merchant and buy back retained sales. Online tabs cover Browse, offers, history, watchlist, vault, verified leaderboard, World Boss, Season and Clan Boss; unavailable services say so in the window.

11 · System, music and cosmetics
