The author initially lost interest in Marathon due to its challenges and competition from Arc Raiders, but recent updates, including enhanced visuals and the introduction of Runner Shells, have rekindled their enthusiasm. The Runner Shells are highly customizable, offering more flexibility than traditional hero selections in other games. Various Runner Shells, such as Destroyer, Assassin, Recon, Vandal, Triage, and Thief, have unique abilities inspired by Destiny, with Thief particularly appealing for its loot-gathering capabilities. The author expresses optimism about Marathon's potential and intends to engage with the game at launch.
