S Tier

Meta-defining picks with the strongest overall value.

#1

Layered Coverage

Core

Front, middle, and cleanup pressure keeps more of the lane useful.

KeepBest for all basesBest for boss baselinesBest for offline stability
Why S tier
Repeated direct gameplay evidence shows layered roles survive more consistently than one crowded point.
#2

Protected Ranged Damage

Core

Weapons such as mortars or Teslas contribute while blocks or traps absorb pressure.

KeepBest for wave clearingBest for boss pressure
Why S tier
Multiple reviewed videos place ranged damage behind or around delaying roles.
A Tier

Very strong choices that fit most players and scenarios.

#1

Front Delay and Trap Pressure

Foundation

Blocks and traps establish first contact and protect the damage layer.

KeepBest for beginnersBest for opening waves
Why A tier
It is essential support, but it needs middle and cleanup coverage.
#2

Middle Recovery Layer

Structure

A second contributing layer catches survivors from the opening.

KeepBest for higher wavesBest for inconsistent openings
Why A tier
A repeated second layer is a consistent recommendation across layout videos.
#3

Cleanup Coverage

Safety

Final pressure before the core protects against leaks and boss survivors.

KeepBest for boss testsBest for offline layouts
Why A tier
It is valuable when enemies pass the main group but should not replace opening coverage.
C Tier

Playable, but usually outclassed by better options.

#1

Rarity-Only Stacking

Risk

Choosing objects only by rarity without testing their lane role.

Consider rerollingBest for collection display
Why C tier
A rare-looking object still fails if it cannot contribute to the current lane.
