Quick Guide
  • I Am Your Beast in the trenches S rank runs demand speed, momentum, and clean extraction above raw kill counts
  • Route first: memorize objective placement and enemy positions before chasing a faster time
  • Chain eliminations: high ratings reward continuous combat flow, not cautious duels
  • Skip optional fights: only engage enemies who block the objective or the escape route
  • Replay in layers: fix your route, then your combat, then combine them into one run

How S Rank Scoring Works on In the Trenches

I Am Your Beast is built as a score-attack FPS: short, replayable missions where the result screen grades your completion time, combat flow, and objective execution. In the Trenches follows the same rules as every other mission in the campaign — the S rank is earned by turning a successful clear into a fast, controlled run rather than by hunting every enemy on the map.

Three factors shape your final rating on this mission:

Scoring FactorWhat It MeasuresS Rank Target
Completion timeTime from level start to extractionMinimal detours, no backtracking
Combat efficiencySpeed and flow of eliminationsChained kills without long pauses
Objective executionClean completion of mission tasksNo failed interactions or resets
Read the Result Screen First

Before changing your strategy, finish one full clear and study the mission result screen. It tells you whether time, combat flow, or movement is the weakest part of your attempt — fix that element before anything else.

The mission's trench layout rewards players who treat movement as part of every attack. Standing still — even for a moment to reload — gives grouped enemies time to establish sight lines and surround you, which destroys both your time and your combat rating.

Route Planning: Objective to Extraction

Every strong S rank attempt on In the Trenches starts before the first shot. At level start, identify the primary objective, note the direction of the extraction route, and find the shortest line that connects the two.

Opening Route

  • Move along the edge of the combat space
  • Use cover to cross exposed sections
  • Approach isolated enemies before groups

Objective Area

  • Approach from cover first
  • Remove the closest threat to the interaction point
  • Plan the exit before starting the interaction

Final Approach

  • Save a direct movement line for the escape
  • Eliminate only enemies controlling the path
  • Sprint through the exit without stopping
The Most Common S Rank Killer

Many failed runs come from continuing to fight after the level has already been won. Once the main task is complete, stop taking risks and follow the extraction route. Optional kills only matter when an active challenge requires them.

Combat Chains and Weapon Choices

Improvisation is the core of I Am Your Beast combat. There is no fixed loadout — the best weapon is the one that matches the current distance, enemy formation, and escape route. Use this comparison to pick the right tool for each section of the trench:

ToolIdeal RangeBest Use in the TrenchesKey Limitation
Melee attacksPoint-blankIsolated enemies, ammo conservationRisky against grouped sight lines
PistolShort-mediumRemoving the enemy blocking your next movement lineWeak against packed clusters
ShotgunCloseBreaking through tight trench sectionsLoses value at distance
Assault rifleMediumOpen areas with spread-out threatsEncourages slow positional play
Thrown objectsShort-mediumDisrupting groups, opening routesWasted on single low-priority targets
1

Separate targets

Use trench corners, cover, and movement to pull enemies away from their group before committing to a melee or close-range attack.

2

Strike and move

Complete the elimination, then immediately reposition. Never stand over a defeated enemy — the next threat is already aiming.

3

Chain into the next encounter

Carry momentum forward. Treat melee, firearms, thrown objects, and environmental hazards as parts of one continuous combat sequence.

4

Break formations with the environment

When a group blocks the route, use explosives or hazardous objects to disrupt them instead of fighting from one position.

5

Exit cleanly

Once the route opens, leave the combat area. Do not return for optional kills during a scoring attempt.

Momentum Is Score

High-level attempts reward sustained combat flow. A run with five fast, chained eliminations typically scores better than one with eight slow, separated kills — keep attacking without losing momentum.

Five-Step S Rank Improvement Routine

Fast, repeatable improvement follows a layered process. Fix one element at a time and only combine them when each part is consistent:

StageFocusGoal
1. Safe clearMission layout, enemy placement, objective orderUnderstand the full route
2. Downtime reductionFast transitions, minimal backtrackingRemove pauses between encounters
3. Combat chainsContinuous eliminations, combo preservationSustain combat flow
4. Section practiceReset discipline, consistent openingsStabilize weak sections
5. Full optimizationTime, efficiency, and rating togetherReach the S rank target

Your S Rank Checklist:

  • Complete one safe clear and study the result screen
  • Memorize objective placement and the extraction route
  • Remove all unnecessary detours and reload pauses
  • Practice the two hardest sections in isolation
  • Combine route and combat tactics into one full run
Reset Discipline

Reset attempts that lose too much time instead of finishing them. Isolate the section causing failures, repeat it until consistent, and return to full runs only when your opening route is reliable.

Common Mistakes That Block S Rank

Avoid These Run-Enders
  • Clearing every enemy before moving forward — eliminate only threats that block progress
  • Fighting the whole group from one position — reposition after every attack
  • Chasing fleeing or distant enemies outside challenge requirements
  • Stopping to reload or search for a perfect loadout during the escape sequence

Treat extraction as its own encounter. Keep a reliable close-range weapon ready for the final approach, keep moving, and use the route you planned at the beginning unless enemy positions have changed.

FAQ

Q: How fast do I need to be for an S rank on In the Trenches?

There is no single fixed time to quote — the S rank depends on completion time, combat efficiency, and objective execution combined. Use the mission result screen after a successful clear to see which factor is holding your rating back, then improve that element on the next run.

Q: Do I need to kill every enemy for an S rank in I Am Your Beast?

No. Eliminate only opponents who block the objective or the extraction route. Optional kills cost time and often lower your combat flow rating unless a specific challenge requires them.

Q: Which weapon works best for the I Am Your Beast in the trenches S rank run?

There is no fixed loadout. Melee works best against isolated targets in tight sections, the shotgun breaks clustered groups, and thrown objects or explosives disrupt formations. Switch tools based on distance and enemy density rather than keeping the first weapon you find.

Q: Should I practice the whole mission or specific sections?

Practice sections. Reset attempts that lose too much time, repeat the sections causing failures until they are consistent, then return to full runs once your opening route is stable.
