Battle Simulation 'Samus Aran' is a test alluded to in a panel in the Phazon Mines. In the GameCube version, it is found in Omega Research, but in the Wii and PAL versions, it is found in Elite Control.
"Test results from Battle Simulation 'Samus Aran' are promising. Elite units report a 74% success ratio against Aran in testing. High Command is pleased, but expects a higher ratio by project's end."
