New Weapon
This build sharpens the identity of the LMG slot and clarifies how key entries are expected to perform in firefights.
- Weapon role: LMGs are positioned for sustained suppression rather than burst dueling.
- Reload timing: Reload time increases are aimed at supporting larger magazines and encouraging deliberate positioning.
- Volt LMG: Framed as a suppression focused option built to keep targets pinned while squads maneuver.
- F55: Retains its portable minigun identity, emphasizing continuous fire and space control.
- Handling and cadence: Updates align behavior with intended role and timing, matching the adjustments listed for this cycle.
Med Gel Detailed Breakdown
Medical flow in ships changes meaningfully in PTU 4.3.1 with MedGel integration into respawn rules.
- Purpose: Ship medical beds now require a MedGel resource to enable respawn, shifting from unlimited respawns to a consumable dependent loop.
- Usage: Bed activations consume MedGel, making resource planning part of operational readiness during longer sorties.
- Behavior: Medical respawn logic and resource application receive corrections in this build to align with the new rules.
- Notes: Medical resource status can briefly desync after respawn in high load scenarios before correcting.
Onyx Facility New Wing Overview
Onyx Facilities see expanded mission coverage to diversify routes across the investigation spaces introduced in 4.3.0.
- Scope: The same facilities gain additional objectives, creating more varied runs through familiar layouts.
- Flow: Mission interactions and objective progression receive corrections to smooth out pacing.
- Reliability: Focused fixes target steps that could stall under specific multiplayer timing conditions.
New Features
This update builds on 4.3.0 content and layers in new encounter dynamics and medical rules.
- Onyx Facilities Expansion: The investigation locations introduced in 4.3.0 gain expanded mission content, broadening objective coverage for more varied runs.
- Pyro Dropship Reinforcements And Watchtowers: Dropships now respond at various Pyro outposts based on local population. Watchtower presence influences how reinforcements engage, adding reactive pressure to active locations.
- MedGel Medical Respawn Resource: Ship medical beds require a resource to enable respawn. This ties bed respawns to MedGel, shifting them to a consumable dependent loop.
