Quick Guide
  • S Rank in I Am Your Beast is earned through completion time, combat efficiency, and objective execution together.
  • Route memorization comes first: learn enemy positions before chasing fast times.
  • Combat chains — linking eliminations without pauses — raise your score more than isolated kills.
  • Replay discipline: reset failed attempts early and practice short sections, not full runs.
  • Result screen analysis shows exactly which scoring category is holding your rank back.

How S Rank Scoring Works in I Am Your Beast

I Am Your Beast is built around short, replayable missions scored on your performance. If you want to know how to get S Rank, start by understanding that the mission rating is not based on time alone. The result screen evaluates several categories, and a weak score in any one of them can block the top rating even when your clear time is fast.

The core scoring inputs are:

Scoring FactorWhat It MeasuresImpact on S Rank
Completion timeSpeed from mission start to extractionMajor; slow routes cap your rating
Combat efficiencyHow quickly and cleanly threats are removedMajor; drawn-out firefights hurt score
Objective executionCompleting required tasks and interactionsRequired; missed objectives block rating
Movement qualityContinuity between encounters, minimal downtimeSignificant; hesitation lowers flow
Bonus objectivesOptional challenges per missionBoosts overall mission result
Read the Result Screen First

After every attempt, compare your category scores before replaying. Fixing the weakest category — not just shaving seconds — is usually the fastest path to S Rank.

Step-by-Step Route to S Rank

Follow this progression to move from a first clear to a reliable S Rank run. Each stage builds on the previous one, so do not skip ahead — attempting a fast time before you know the route usually produces inconsistent results.

1

Clear the mission safely first

Complete the objective and extraction without chasing score. Map out enemy positions, objective locations, weapon pickups, and traversal shortcuts. A safe clear teaches you the layout that every later optimization depends on.

2

Build your optimal route

Identify the shortest line from spawn to objective to extraction. Cut detours, remove fights that do not block progress, and note where each weapon pickup fits into the route rather than interrupting it.

3

Eliminate downtime between encounters

Move between fights without stopping. Avoid mid-route reloads, backtracking, and hesitation at doorways. Downtime is the most common reason a clean route still misses S Rank.

4

Chain your eliminations

Treat each mission as one continuous combat sequence. Combine melee takedowns, picked-up firearms, thrown objects, and environmental hazards so kills flow into each other instead of becoming separate encounters.

5

Iterate using the result screen

Compare each attempt against the scoring categories. If time is strong but combat is weak, add more aggressive chains. If combat is strong but time is slow, shorten the route. Reset early when an attempt falls apart.

Do Not Over-Clear

Fighting every enemy on the map is the most common S Rank killer. Eliminate only the threats that block your route or objective, then keep moving.

Combat Chain Strategies for Higher Scores

Combat efficiency is where most players gain or lose their S Rank. The game rewards improvisation — the best tool is whichever one resolves the current encounter fastest, not the strongest gun you can find.

Melee-First Flow

  • Fastest takedowns on isolated targets
  • Conserves ammunition
  • Keeps you moving forward

Weapon Scavenging

  • Take weapons from defeated enemies
  • Match tool to distance and enemy density
  • Never wait for a "perfect" loadout

Environmental Kills

  • Hazards and explosives hit groups at once
  • Satisfies bonus objectives
  • Removes multiple threats in one action
Encounter TypeBest ToolWhy It Works
Isolated enemy near your routeMelee takedownInstant, silent, no aim downtime
Clustered group in tight spaceShotgun or explosiveBreaks formation in one action
Distant target blocking a crossingPistol or rifleClears the path before you commit
Group near a hazardEnvironmental triggerMulti-kill plus bonus objective credit
Final approach to extractionAny remaining firearmKeeps momentum without stopping
Separate Experimentation from Runs

Practice special actions and bonus kills in dedicated attempts, not during a strong S Rank run. Mixing both goals is how clean runs get ruined.

Common S Rank Mistakes and Fixes

Most failed S Rank attempts trace back to a handful of avoidable habits. Diagnose your runs against this table before grinding more replays.

MistakeEffect on ScoreFix
Clearing every enemyTime bloat, lower flowSkip fights that do not block the route
Stopping to reload mid-routeDowntime penaltyReload during transitions or scavenge weapons
Fighting after objective completesWasted time, added riskExtract immediately once the task is done
Fixed loadout obsessionSlower encountersImprovise with pickups and melee
Full runs after a bad openingInconsistent practiceReset early and drill the failed section
Ignoring bonus objectivesMissing score boostPlan them into the route on later replays
Reset Discipline

If the opening 10–15 seconds go wrong, reset. Practicing short sections until they are consistent produces better S Rank runs than finishing every attempt.

Your S Rank Run Checklist

Track these milestones as you work each mission toward S Rank. Completing them in order keeps your improvement measurable.

S Rank Milestones:

  • Clear the mission once without chasing score
  • Memorize the optimal objective-to-extraction route
  • Complete a run with no avoidable downtime
  • Chain at least three eliminations without pausing
  • Finish all bonus objectives for the mission
  • Achieve S Rank using the result screen to guide fixes

FAQ

Q: Is S Rank in I Am Your Beast based only on completion time?

No. The mission rating combines completion time with combat efficiency, objective execution, and movement quality. A fast run with messy, drawn-out fights can still fall short of S Rank, so balance all categories instead of only racing the clock.

Q: Do I need to kill every enemy to get S Rank?

No. Over-clearing is one of the most common reasons players miss S Rank. Eliminate only the enemies that block your route or objective, then keep moving toward extraction.

Q: Should I chase bonus objectives during my first S Rank attempt?

Separate the goals. Earn your S Rank on a clean, fast route first, then replay the mission to complete bonus objectives such as melee-only or environmental kills once the route is stable.

Q: How do I know which scoring category is holding my rank back?

Check the mission result screen after each attempt. Compare your category scores — whichever area is weakest, whether time, combat flow, or objectives, is what your next practice session should target.
