Hey, everyone,

We have deployed** Patch 0.4.2.0** to the live servers. If the update does not appear automatically, please restart Steam to trigger the download.

For a quick summary of what's new, watch this **VIDEO DEVLOG** or read the full **CHANGELOG **below.

##### **Overview**

Patch 0.4.2.0 introduces fixes for various community-reported issues and a new experimental feature: **player visibility**, displayed through a HUD widget (more details below). This feature ties into the nighttime lighting adjustments, as **nights are now darker**.

We are also bringing further **fixes and tweaks to AI behavior**. For example, we adjusted AI NPCs' health states in combat to improve their responsiveness during engagements and help them follow their intended tactics more reliably.

Other fixes include wallet improvements that prevent unintended items from being placed inside, as well as a fix for the repair price of the M-201C.

##### New Experimental Feature: Player Visibility

- The distance at which AI NPCs can spot a player is determined by multiple factors and is now displayed in the top-left corner of the HUD

- Visibility distance is influenced by:

- Vegetation: The surrounding vegetation type and density significantly affect visibility. Dense jungle provides significantly better concealment than open terrain. Entering thick vegetation, such as bushes, further reduces the chance of detection.

- Light exposure: Darkness provides better concealment than well-lit areas

- Weather: Adverse weather conditions, such as rain and fog, reduce player visibility for AI enemies

- Player stance: The lower a player stays to the ground, the harder they are to detect

- Movement: Movement increases player visibility. The faster a player moves, the more visible they become to AI enemies

- Noise: Loud actions, such as firing a weapon, temporarily increase player visibility. Using suppressors reduces this effect

Player visibility is an **experimental feature**. We want your **feedback** on what you like, dislike, or would change about it. It is a first iteration, and there are a couple of **known issues** with it that will be addressed in future patches:

- Shadows inside buildings, as well as some light sources (lamps or other players' flashlights), do not affect player visibility

- Player visibility to AI NPCs is reduced too heavily by low vegetation

- Visibility distance is incorrectly reported in the UI while standing within specific biomes
