An experimental man-portable anti-material rifle chambered in .458 SOCOM. It must be manually chambered for every shot. It can be ordered from requisitions.
Originally developed by ARMAT Battlefield Systems for the government of the state of Greater Brazil for use in the Favela Wars (2161 - Ongoing) against mechanized infantry. The platform features an onboard computerized targeting system, sensor array, and an electronic autoloader; these features work in tandem to reduce and render inert armor on the users target with successive hits. The Almayer was issued a small amount of XM88s while preparing for Operation Swamp Hopper with the USS Nan-Shan.
It has a special property - when you obtain multiple direct hits in a row, its armour penetration will increase by 10. At maximum stacks, this will give each XM88 round 50 AP.
