Hi-Cap Mag

The Hi-Cap Mag is a magazine slot weapon mod in Marathon that substantially increases the maximum rounds a weapon can hold, prioritizing raw ammunition capacity above all else. By fitting a high-capacity magazine design, it reduces the total number of reloads needed across an engagement or a series of back-to-back fights, giving runners more sustained firepower before they need to pause. This is especially valuable in Marathon's extraction scenarios where running out of ammunition at the wrong moment can be fatal.

The Hi-Cap Mag differs from the Drum Mag in that it focuses on high capacity without the fully cylindrical drum form factor, maintaining a more standard magazine profile with an extended body. It suits runners who frequently find themselves in extended firefights or who want a comfortable buffer of ammunition when taking on high-density enemy zones. Compared to the Feather Mag and Combat Mag, the Hi-Cap Mag trades away reload speed for a larger round count, making it best suited to weapons with already-efficient reload animations or playstyles where the added capacity justifies the occasional slower reload.
