Holoscreen

A holoscreen is a portable, digital computer monitor that displays schematics and also apparently doubles as a security camera.

SPC M. Angseth complains in her final Log about being confined to staring at a holoscreen during the Splinter infestation, despite believing she could outshoot her fellow soldiers in the GFMC Task Force Herakles. Angseth's body is found in the Trooper Security Station, which does not feature any computer screens that could be definitively identified as the holoscreen she mentioned. It is possible that she was referring to computer monitors found in previous rooms such as Hive Chamber A and Command Chamber, which can be seen displaying images of Federation Marines and converted cargo pod gates by the time Samus Aran enters the Splinter Hive. This would suggest that Angseth was not in the Trooper Security Station when she recorded her final Log.
