Matsu Hunter 199X is a free mod designed for SnowRunner, compatible with the Wheel & Addon Pack for X7B's trucks. This mod introduces a visual overhaul in version 4.0.0, along with a variety of features that enhance gameplay. Players can enjoy default switchable 4x4 and diff lock in low gear, along with 32-inch new wheels that come in chained variants and 3 new rim options. Additional features include multiple suspension variants, a special roof rack for cargo, and fully functional glowing gauges and mirrors that add to the realism of the game.

In addition to the visual enhancements, Matsu Hunter 199X offers players 5 original engine sounds and a map landmark for better navigation. While the mod is packed with features, it is important to note that custom engine sounds do not function on the Switch version, reverting to the default game sounds instead. Players are encouraged to restart the game after updating the mod to address any issues that may arise.
