KF-B "Hole" Middling Chassis
KF-B "Hole" Middling Chassis gives you an 18-cell 4x3 Middling frame, so it is the chassis to compare when a build wants width for side-by-side guns, cargo, and repair space.
KF-Q "Abyss" Royal Chassis gives you a 30-cell 5x5 Royal frame, so it is the square late-game hull to compare when the build wants a balanced center instead of a long ship.
KF-Q "Abyss" Royal Chassis feels better in late-game builds that want a squarer deck. Its 5x5 grid gives 30 cells, which is less total room than the longer KF-L Abyss hull but a more even center for fitting combat rooms, cargo, and support space around each other. That usually makes the whole Trampler feel more balanced instead of turning into a long corridor ship.
It is one of the Trampler chassis options selected in the Trampler Editor before you place compartments and weapons.
KF-B "Hole" Middling Chassis gives you an 18-cell 4x3 Middling frame, so it is the chassis to compare when a build wants width for side-by-side guns, cargo, and repair space.
KF-B "Trench" Great Chassis gives you a 22-cell 5x3 Great frame, so it makes sense when the build wants a long hull for cargo lines, gun rooms, and interior lanes.
KF-L "Abyss" Royal Chassis gives you a 32-cell 4x6 Royal frame, so it is the long late-game hull to compare when one Trampler must carry cargo, crew space, and heavy systems together.
KF-L "Hole" Middling Chassis gives you an 18-cell 3x4 Middling frame, so it is the chassis to check when a build wants more length than the wider Hole variant.
KF-L "Trench" Great Chassis gives you a 22-cell 3x5 Great frame, so it is the long-hull Great option for players who want more depth than the wider Trench layout.
KF-Q "Trench" Great Chassis gives you a 20-cell 4x4 Great frame, so it is the squarer Great option when the build wants a compact center more than raw cell count.
KF-Q "Well" Small Chassis gives you a 16-cell 3x3 Small frame, so it is the tight starter hull to use when the build needs a compact square Trampler instead of cargo-heavy space.
S&H Atm.Fs 77B-L Small Chassis starts making sense when a compact Trampler still leaves enough room for cargo, guns, repairs, and movement.
A 5x5 square feels better when guns, support rooms, and cargo all need to sit around the same center instead of stretching down a long hull.
The tradeoff is total room. The square shape is cleaner to build around, but it gives up cells to the longer 32-cell KF-L Abyss Royal chassis.
Yes, when you want a square 5x5 Royal hull and 30 cells for a more balanced late-game layout.
The 5x5 grid is the key fact. It trades some total room for a squarer interior than the long Royal alternatives.
