The RUST MLRS Aiming Module (Multiple Launch Rocket System) is a unique key-type introduced in the MLRS & Desert Base Update on the 4th of November 2021. This aiming module is required for utilizing the MLRS launching module to fire the MLRS Rockets. The launching mechanism is located at the Abandoned Military Base monument located in the desert biome of appropriately sized RUST procedural maps.
MLRS rockets are a ranged ballistic system used in conjunction with an MLRS aiming module at the Multiple Launch Rocket System. When inserted into the back of the said system and properly targeted, they can be ordered to launch at any given point on the map (indicated by the aiming module process) to inflict devastating raid-style damage to any entity within the targeting circle. You may insert one to twelve rockets into the system at a time and fire when ready. There is a 10-minute cooldown window thereafter before the system may be reloaded and fired again.
When aiming MLRS rockets, a red and a white circle will appear on your targeting screen. The red crosshair circle indicates the desired target location, while the white crosshair circle indicates the area in which the rockets will impact. The rockets impact without prejudice and will damage the enemy and friendly entities and players alike. Upon firing the inserted payload and the vehicle becoming disabled, the rockets inserted will be used and the aiming module will be destroyed. You will require a new aiming module for all further barrages.
