Looking through the lens of file naming conventions: tesys_birth_story_2_v010_loserishome_ark_top.ark This could be a custom ARK save file where "Tesys" is the player character, "Birth Story 2" is the save slot, "v010" is the version, "loserishome" is the base or server name, and "ark top" indicates it’s the primary save for a "top" (advanced) playthrough.
