A recent update to Marathon has introduced the 'CARRI' system, which stands for the "CyberAcme Runner Reinforcement Initiative," encouraging cooperative gameplay among players. This system rewards both solo players and teams for completing contract objectives and successfully exfiltrating together. Players can earn CyberAcme Commendations, which can be spent in the CARRI Armory for various rewards, including weapons and salvage crates. Solo players can earn commendations by completing individual objectives and can receive extra commendations when extracting with others. A new 'toggle to open' setting for proximity chat and an end-of-run feature called 'Stay Together' promote friendly interactions. The update also includes a 'Mercy Kit' for reviving downed players from other teams and introduces eleven new Deluxe Unique weapons, balance changes, and adjustments to gameplay mechanics, such as railgun charging and extraction timers. The update is now live.
